My CorkSport Mods: Keith’s Mazda 3 Sport

I’ve met a lot of amazing people thanks to my Mazda 3 Sport, but Yolanda Sampson (Instagram: @bluehalogirl) is the one I blame for this addiction we call “modding.” When we met, I hadn’t done much to my car yet, just a couple minor things like tinted windows and tinted taillights. She had a feeling I’d be into meeting some more like-minded locals and invited me to a meet. We got along like only two Mazda nuts could, and it was game over for me.

What’s on your mod list for 2016?



Everything A Noob Should Know About The Catback Exhaust

How to choose the perfect catback exhaust.

There you are, sitting behind the computer screen trying to decide which type of catback exhaust you want to purchase. It’s a stressful time considering you want to make sure you’re getting the best possible quality exhaust system.

So, what are some key factors that come into play when trying to make a decision? Is it the diameter of the exhaust that persuades you? How about the type of steel used? Do you care about perfect fitment? These are all things to consider when making a decision on an exhaust.

Here at CorkSport, we make it our number one priority to meet the expectations of our customers. Whether you drive a Mazdaspeed 3 or a regular Mazda 3, we’ve made sure to engineer a perfect fitting exhaust that maximizes engine performance.

Take the Mazdaspeed 3 for example: When you purchase a CorkSport Catback Exhaust, you’re getting T304 stainless steel piping that has been polished to a mirror-like finish.

Everything you need to know about upgrading to a catback exhaust.

You’re also getting true 80mm piping, which is slightly bigger than three inches, making our exhaust one of the biggest bolt on catback systems.

What to consider when choosing an upgraded exhaust system.

Fitment is also a big concern to us. We make sure our exhaust systems are mandrel bent and TIG welded to make a perfect bolt on fitment.

Now that you know our exhaust is 80mm piping, polished to perfection, and made to be a direct fitment, you can bet this exhaust will increase performance and sound. By installing our catback exhaust, you’re removing the secondary unmonitored catalyst making the exhaust flow much faster out of the motor. By increasing velocity of exhaust gases out of the motor, you increase power and make your turbo spool up a little bit faster.

Among the power gains you’ll see from installing the CorkSport Catback Exhaust, you’ll also have a car with a deep growl to it. Our exhaust has one of the best sounding tones on the market. With a quality made exhaust, comes quality sound.

When you’re ready for a catback exhaust, make sure to check out what CorkSport has to offer to ensure you get the highest quality parts.

Product Release! CorkSport 2013+ CX5 Axle Back Exhaust

The new Mazda CX5 is a striking vehicle, the flowing lines of it’s “Kodo” design language are somehow angular and graceful at the same time. Such a design was begging for a quality exhaust to match its’ looks and enhance its’ sound. With that need established, the engineers at CorkSport attacked one of the first 2013 CX5’s in the United States and set to improve on an already stellar car.


CorkSport Mazda CX-5 Exhaust

Constructed using T-304 stainless steel from flange to tip and weighing a full 8lbs less than the stock exhaust, the CorkSport exhaust not only performs better but brings a deeper, more aggressive sound to the CX5 as well.

Product Release! CorkSport SkyActiv Mazda 3 Power Series Single Exit Exhaust

CorkSport is pleased to expand our single exit exhaust offering to include the new Mazda 3 SkyActiv model!

The CorkSport Power Series Single Exit 60mm Exhaust has been designed to work with both the 2010+ sedans and hatchback trim standard 2.0 liter and SkyActiv engine models.

Featuring dual resonators, a slip fit compression connection to the aft end of the catalytic converter and a single tailpipe design, the CorkSport Mazda 3 exhaust replaces the factory tailpipe muffler with polished 2.4 ID stainless steel piping and non-resonated CorkSport dual wall 90mm exhaust tip.

During testing with the CorkSport SRI and single exit exhaust on the 2.0 liter model, the CorkSport Mazda 3 Power Series Single Exit Exhaust went from a baseline of 118hp/110lb ft. of torque to a respectable 135hp and 123lb ft. of torque at the wheels.

The 2.0L results are moderate at the bottom end (with around a 4-5hp/tq gain) below 4000rpm with the majority of the power coming on rapidly at around 4500rpm and held steadily to the 7000rpm redline demonstrating the constrained nature of the stock system for the smaller 2.0L engine.

As with all of our CorkSport exhausts, the Power Series Mazda 3 single exit design features mandrel bent, polished stainless steel T304 construction for corrosion resistance and a clean stylish look. It has a distinctive performance sound that is mild but noticeable at cruise and idle and a distinctive growl at wide open throttle and free rev.

The CorkSport Power Series Mazda 3 SkyActiv Exhaust includes an optional 60mm racepipe with or without high flow catalytic converter that attaches between the factory header downpipe flange and the front compression fitting of the cat-back portion of the exhaust system

The CorkSport Power Series Mazda 3 SkyActiv Single Exit Exhaust begins at $399 for the sedan model and $419.00 for the hatchback model. For more information and complete pricing, please visit our product listing page at

CorkSport 2010 Mazdaspeed 3 – The Tireless Worker

CorkSport currently develops parts to support 22 Mazda models and at times one of the trickiest parts of designing parts for all of these cars is finding a car to use during the development process.

Occasionally it can be hard to source a car and find someone who is willing to let you start cutting on their brand new car, which is why it is so great to have our 2010 Mazdaspeed 3 at the shop to use for product development.

Many of you have seen pictures of the CorkSport Mazdaspeed 3 and say how great it looks, but little do you know that it’s a true workhorse.

In the past few months I have seen more parts go on and come back off of this car than I ever would have guessed. Hardly a day goes by when something is not being done to it to further development of our Mazdaspeed 3 line. In the past couple weeks alone it has had three different exhaust combinations on it and at one point even had a TMIC on it for a day while the FMIC piping was still installed but disconnected.

One of the great parts of being an engineer for CorkSport is not spending all day sitting at a desk. I’m able to get out and actually work on a car, put it on the lift, prototype parts, test fit samples, and get some actual real world testing on our new parts. This allows us to develop top of the line parts that have been thoroughly tested in real world environments on a shortened development schedule because we don’t have to develop, send parts out to identified R&D cars, wait for feedback, then tweak the design and start the process all over again. Being able to just walk out into the shop to look at something or install a prototype for testing is great. We can get immediate results so we can get the product out to you, the customer sooner.

We recently released our Front Mount Intercooler Kit for Short Ram Intake and some of you with large power aspirations had questions about the fitment of a larger intercooler. The kit we released with the 24x 6x 3.5″ does not require you to remove the crash bar and in order to accommodate a larger intercooler, removal of the crash bar is necessary. Having our shop car not too far from my desk, I was able to go out and fit a larger intercooler onto the speed 3, prototype some brackets, test and then adjust the design to accommodate the larger intercooler core in just over a month. We now have an option for those of you that want to upgrade your turbo and run a CorkSport FMIC for SRI. The new larger intercooler core is 24x 11x 3” and can support up to 700hp.

Having the car here also means we get to drive it and experience how new parts will act in the real world. We can find out how it handles in stop and go traffic, how comfortable it is on the freeway, and how it looks driving down the road. A couple days this week I was able to drive the car to and from work and I can definitely say that even with all of the performance parts installed, the car is still a great daily driver.

I must say having a car like the CorkSport 2010 Mazdaspeed 3 available to use as a development tool really helps us create the best possible product for CorkSport customers.

2010 MS3 – Best Way to Get 40+ HP Without Becoming an Amputee, Divorcee, or Both

I recently received an email asking which CS part combinations would be the best way to achieve a 40+ horsepower gain in the 2010+ MazdaSpeed 3 without breaking the bank, or having your significant other make you call and cancel your order.

Your new MS3 breathes just like you do. Maximizing the intake of air and freeing up the expulsion of used gasses (exhaust) will help your vehicle breath better, and go faster.

On the intake side of things, for $239 you can get our Short Ram Intake which includes our mandrel bent turbo inlet pipe and custom designed MAF housing and silicone coupler. This will free-up flow into the turbo and allow your MS3 to breath deeper. The average gains seen here are 10-15 hp.

For exhaling, you want to expel all those used gasses as quick as possible. With the CS turbo-back exhaust, you are reducing the back-pressure and allowing your MS3 to utilize the potential of its turbo. The kit comes with Corksport’s full 80mm catback dual exhaust, racepipe, and downpipe. This setup will give the average MS3 owner 28-31 hp at the wheels for just over $1,000 for all 3 parts.

Shown below is our 2010 Mazdaspeed 3 with the CorkSport Short Ram Intake & Turbo-back exhaust compared to our car completely stock. The before number is 226 hp and came out to 272 with the SRI and Turbo-back exhaust. That is a 46 hp increase to the wheels with two products.

This is my suggestion on the easiest and cheapest way to gain 40 hp at the wheels. If you have a different/better way to do this using CS products, I would love to hear your comments.

For those of you on more of a budget, may I suggest just the Short Ram Intake ($239) and racepipe ($149)? For a total price or $388 you can get an increase in wheel hp of upper 20’s to lower 30’s.

Any more questions feel free to shoot me an email.


Finally! The 2010 MazdaSpeed3 Downpipe Released!

It’s released! The downpipe for the 2010 Mazdaspeed 3 is on our shelves and ready to ship out. First off lets cover the obvious questions, why install a downpipe? When installing an aftermarket down pipe several things happen. First the turbo charger requires less effort to quickly spin up due to the removal of the catalyst, so boost will happen at a lower RPM. Secondly, with less restriction and back pressure the turbo will be able to quickly expel more exhaust gases, thus raising the boost and increasing power across the vehicles entire power band.

Check out our technical write up about performance exhaust downpipes here.

The CorkSport Mazdaspeed 3 Power Series Downpipe gives you faster turbo spool up which results in a larger power band. Gains in power have been up to 21 wheel horse power when installed on an otherwise stock Mazdaspeed 3.

The downpipes on the 1st Gen MS3 have historically been a bit of a puzzle to work around however our designs are able to avoid throwing a check engine light on first generation DISI equipped vehicles. Other manufacturers of downpipes are hit and miss depending on the manufacturer, with some throwing the occasional random CEL for slow response time and others being more pervasive.

The 2010 models are a bit more elusive and harder to pinpoint the ideal sweet spot for the secondary oxygen sensor that will not throw a check engine light. We are however actively working on resolving the CEL and if successful we hope to offer a retro fit kit for previously purchased downpipes.

If you have any questions about the 2010 MS3 downpipe feel free to shoot us an email or give us a call. We’ve got several more things coming down the pipe so stay tuned.


Staged Dyno Results for 2010 MazdaSpeed3

We have received a lot of questions regarding the dyno numbers for our products for the 2010 Speed3. So far we’ve only released a Stock vs. (Intake+RacePipe) dyno sheet, and I figured it was time to add some clarity to the questions and comments in a centralized location instead of replying on specific forums and leaving other people in the dark. In the end, our Intake + Racepipe + Downpipe give customers the ability to crank out 51 more horsepower for $687. The key to getting the most out of your car isn’t just to make ample power increases, but to have money left in your wallet to add more options sooner. CorkSport has you covered at a cost of $13.74/hp with a peak gain of 51 Wheel Horsepower and 47 Ft Lb of Torque.

The 2010 Speed3 has a lot of power left on the table, and our product development has really brought that to light. Unfortunately, we stage build everything -starting with an Intake, adding a RacePipe, then the DownPipe…and Dyno and labor hours add cost to parts, so we try our best to get the data we need to validate our products without adding a lot of cost to the parts based on a variety of test iterations and combinations. This blog post details the results of the staged build on our 2010 Speed3. In addition, it makes some details clear about comparing our systems to other options on the market -what’s included in intake and downpipe packages to provide detail to costs vs. gains.

Stock vs. Power Series Intake System
Our $239 intake system includes our aluminum turbo inlet pipe, billet MAF housing and CorkSport Dry Flow Air Filter. Again, this package includes the turbo inlet pipe -it is the only system on the market that is packaged including the inlet pipe -all others are marketed separately. The torque gains were nearly 20ft lbs increase on average. We also saw large sections of torque gain that were up to 33ft lbs of torque. The horsepower gains were equally impressive with the largest differential being a 36whp gain over the stock numbers. Our system works great, we have put a lot of time into the design and validation testing of it and it generates some serious power…at $6.63 per horse at the wheels.

Racepipes and Downpipes…*
The CorkSport TurboBack Exhaust packages are broken into three components: The Downpipe which evacuates exhaust gasses from the turbocharger into the main exhaust system; The Racepipe (available with or without high flow catalytic converter) which replaces the factory secondary restrictive catalytic converter; The CatBack Exhaust System which is comprised of the primary 80mm (3.15″) exhaust pipe and resonators and the dual 80mm tailpipe section. The main component to discuss is the comparison of the CorkSport Downpipe and Racepipe to other Downpipes on the market. A few other Downpipes cost substantially more -due partially to the fact that they include what we sell as a Racepipe. Despite our separate packaging, our pricing is still competitive at $448 for the combined package, and allow our customers to swap in the wide open 80mm Racepipe on track days and retain their factory catalytic converters or choose the Racepipe which features a high flow spun metallic catalytic converter (an additional $200). Whether you choose the Downpipe/Racepipe combination with or without a high flow catalyst, you’ll find our prices aggressively competitive.

Stock vs. Power Series Intake System + Power Series Stock Fitment Racepipe
This stage adds the Power Series RacePipe to the 2010 Speed3 w/ CorkSport Short Ram Intake & Turbo Inlet Pipe. Power goes up nicely to a combined gain of 41whp and 33ft lb of torque at peak and a blistering 50ft lb of torque at 3000rpm. Where the intake alone dropped low end (1600-2900RPM) torque by a few pound feet relative to stock, the addition of the racepipe puts the entire torque curve higher than that of the stock setup. If you’re running a rally car or just want blistering torque -this is your prime combination.

Stock vs. CorkSport Intake + Racepipe + Downpipe
This stage adds the Power Series Downpipe from CorkSport to the 2010 Speed3 w/ Short Ram Intake & Turbo Inlet Pipe. The CorkSport downpipe features a divorced wastegate dump design -providing a separate outlet for wastegate gasses and avoiding disruption of the primary exhaust pathway when the wastegate cracks open to bypass excess exhaust pressure past the turbine wheel. Adding the downpipe to the previously detailed combination of intake and racepipe, power jumps another 10 horse at the cost of a little bit of peak torque, but the low end of the torque curve increases nicely. As a combined package, the CorkSport Intake, Racepipe and Downpipe put down 51 horsepower and 47 pound feet of torque at the wheels. Watch for the release of our downpipe for the 2010 Speed3 in the coming weeks.


* Consult with your local governing body regarding the legality of removal of a factory catalytic converter, whether it is for track or for street use and whether you are using the full race open pipe or a high flow catalyst. High Flow Performance Catalystsare ILLEGAL in the State of California, and will NOT be sold into California.

2010 MazdaSpeed3 First Dyno Results

MazdaSpeed3 Dyno

Just got got the 2010 Mazdaspeed3 off the dyno after doing some installs and have some results to share.

The Dyno run went great for the 2010 MS3. It’s bone stock with three mods – CorkSport Power Series Racepipe (80mm with factory 65mm outlet) and CS Power Series Intake w/ Turbo Inlet and a set of CorkSport Motor Mount Inserts. Each of these products will be released shortly for the 2010 MS3 including some revised design considerations for the new 2010.

The stock baseline numbers for the 2010 were 231hp 269tq (73.8F/45%Humidity). With the two mods, it hammered down 272hp and 301tq (78.7F/43%Humidity).

41hp gain, 32ft lb of torque. Boost went from factory 16.4psi to 18.6. $388! Can’t wait to see what it picks up with the downpipe.

If you have a Speed3 without any exhaust modifications or haven’t added an intake or a turbo inlet pipe, hit me up…there’s power on the table right in front of you.
