All About That CatBack Exhaust

Mazda Catback Exhaust Installed

Ever wondered the key factors of making a decision about your aftermarket exhaust? Why Cat-back? 

Is it the diameter of the exhaust that says performance? Or is it the type of metal used? What about fitment to your current setup? None of these questions by themselves answer what you need by themselves, but all of them together help when making the decision on how to get more power out of your Mazda.

At CorkSport, we have made it our #1 priority to make our customers dreams a reality. Whether you drive a Mazdaspeed or a regular Mazda, we’ve made sure to engineer a great fitting exhaust that maximizes engine performance.

Check out the Cat-Back Exhausts by Car Model Below:

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.

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.

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 cat-back exhaust, you’re removing the secondary unmonitored catalyst making the exhaust flow much faster out of the motor. By increasing the 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 find yourself ready for a cat-back exhaust, be sure to check out CorkSport to ensure you get the highest quality for your ride.

 

Brett’s Build Part 3

Well guys, I am back with a part 3. I apologize in advance for the delayed release of the 3rd chapter, but the Mazda was out of commission for a bit getting some stuff reworked! That being said, we can now pick up where we left off in part 2!


As I started to settle into my new stake at CorkSport, I started adding on lots of new goodies. At the beginning of the new year of 2017, I got to throw on our prototype Stage II RMM and get rid of my old one for some testing and feedback. Not only did the vibes decrease substantially, it also held the powertrain better and was helping my wheel hop significantly. So while I was at it, I threw on a Lower Tie Bar to help even further, knowing I had plans in the very near future to make over 400 Whp.


It was now Feb. of 2017 and I knew I was wanting to reach my new power goal by Summer. So, I talked to my tuner, Erik with Drama Tune, and scheduled to fly him up here in March to dyno tune the car. I had every single piece needed to complete the 400+ Whp puzzle.

The last missing piece was fuel. At this point in time, I had two options, Port Injection or Methanol Injection. Given, that I only needed a little more fueling head room freed up I went with methanol for ease, and price. For those that are curious, I purchased the Snow Performance Stage 3 Kit.  

I started installing the kit at the beginning of March 2017. Since I was going to be putting bungs into the FMIC piping, I got the kit powder coated as well.  I installed one small nozzle right off the cold-pipe of the intercooler, and another large nozzle right before the throttle body. I left a couple inches to help the alcohol atomize. The total amount I was spraying between the two nozzles was approximately 1000 CC’s of 100% Meth as we were using it for Fuel.  

So, with the car ready my Tuner flew up and we got my car on the Dyno! Keep in mind my car is a stock bottom end, so I knew I was going to be playing with fire a bit. The general rule of thumb here: If you are on a stock bottom end and want to push the car in this fashion, always have a backup plan ready in case the engine gives out.

By the end of the session, I had 3 maps from Erik:

Pump Gas: 340 Whp

E85 Blend (3 Gallons): 390 Whp

Methanol Injection: 430 Whp. (e85 still in the tank for added knock resistance and cooling)

The torque was kept down as much as possible at 380 Ft-lbs @ 4700 RPM. So, the stock rods definitely were not in danger. Ultimately if the block were to give out in this situation, it would more than likely be the piston rings. The stock Piston Rings do not like high heat or harsh temp changes. So, the best thing you can do pushing 400+ hp on the stock bottom end is to allow time between pulls for everything to re-stabilize. This will ultimately increase the time you have before it ‘Splodes. Because, if we are being honest with ourselves, at that power level, its always a matter of when, not if with the stock block.

 



So, this is how my MS3 has been for the last year or so power wise. Built block will be in the future soon. But on this next part, I’ll dive into some cosmetics details that I’m sure a lot of people wants to know.

Why Lowering Springs?

Everything to know about lowering your Mazda with lowering springs.

Whether you want the better handling that comes with the lowered center of gravity, or you want to rid yourself of the wheel gap eyesore.  Lowering springs will give you want you’re looking for.

For running the track, or a spirited drive through the countryside, CorkSport lowering springs are the upgrade you’ve been looking for. By adding lowering springs and lowering the center of gravity of your Mazda allows the car to stay more planted to the road.

One of the biggest things to note on stock suspension is how far upward the suspension travels when hitting a bump. It can make the car feel like it wants to lift off of the road; depending on how fast you’re taking corners. Lowering springs help to correct the car’s suspension travel when you hit a bump in a turn.

Lowering springs also have about 25% increased stiffness. For the Mazdaspeed platform, increased stiffness in the rear is a must. Mazdaspeeds like to squat pretty hard when hitting full boost, so any way you can manage to stiffen up the rear is a great modification for your car.

Adding lowering springs also gives your baby amazing eye appeal and a much more aggressive look. Whether you drive a Mazdaspeed3Mazdaspeed6Mazda 3, Mazda 6, CX-5, CX-3 or MX-5, lowering springs will get rid of that ugly wheel well gap. The result is a Mazda that carries a much cleaner and more aggressive look and gives you the ability to take it to the track if you want to.

Drop your Mazda for an aggressive look and better handling with the CorkSport lowering springs.

Some people want to drop their Mazda as much as possible, and some don’t. CorkSport lowering springs don’t deliver a super aggressive drop. If you’re not interested in scraping your front bumper on every road bump, the CorkSport lowering springs have the right drop for you, and provide the increased handling capabilities you’re looking for.

 

If you’re curious about other suspension pieces for your Mazdaspeed, check out our Struts and Shocks combo kits, that give you just what you need for suspension.

The Race Car Romance

I recently had the opportunity to interview one of my favorite up and coming racers and wanted to share with you some of her advice and story. This is just an awesome look into the winning mentality of one of SCCA’s Wendi Allen Scholarship prominent women Racers! From where she started to where she’s headed and some info in between, you’ll get a chance to hear direct from Johanna Foege in this interview.

How long have you been racing? What got you started?
My brothers both got involved with auto-crossing while I was in college and were always trying to convince me to come out and race with them. It wasn’t until the end of 2011 when a friend offered me a codrive in their Mazda3 (and a year after I purchased my first MazdaSpeed3) that I finally gave it a try.

At that first event, I ended up taking first in my novice (open) class of 7, on my first run, nonetheless! Naturally, I was immediately hooked.

What have been the best outcomes for you since starting racing?
This year I received the SCCA Wendi Allen Scholarship. I suppose this means that I’ve made enough positive impressions on SCCA members to have been nominated for this award, which is intended for young women drivers that show promise at driving and inspiring other women. This scholarship has made a crazy year of racing possible for me, and I’m so grateful to have received the recognition and the opportunity to compete in 8 national tour events throughout 2018!

What have been your best standings thus far?
My first taste of victory was at a local event in Champaign, IL when I took the fastest run of the day (out of all the drivers), in the Mazdaspeed6 back in June 2014. I’ve only made it to one National event which was in September 2017 at Lincoln, NE, but I managed to trophy there, finishing 3rd in my class. And just last week at the Championship Tour Event in Peru, IN, I managed to finish 16th out of 275 drivers.

What do you believe is the best MOD for racing – if you had to pick the best one?
I think this entirely depends on your car and the kind of racing you do! For autocross, the rear sway bar has been my favorite in my Mazdaspeed3, as it helps combat the understeer, pushy front wheel drive characteristics. My favorite mod on the Mazdaspeed6 has been the custom valved, high spring rate coilover setup since that car has relatively soft suspension and a lot of body roll from the factory.

What is your favorite MOD – other than the Driver Mod, which we know you invested in already?
If awesome tires count as a mod, definitely that! All other mods depend entirely on how much grip your tires have on the surface at any given moment. This applies to the street, too. Also, have you seen our Hoosiers? 😝

What has been the most memorable mistake you’ve made on the track?
At 2017 SCCA SOLO Nationals, I had a KILLER run- 0.7 seconds faster than the rest of mine, and 0.5 seconds ahead of first place in my class. I’d been working on looking ahead while driving throughout the year and was doing such a good job of this that I hit a cone that was right in front of me on that run. I remember seeing it at the last second and thinking, “There’s no way I’m getting around that now!” What I didn’t know at that moment, was that cone was going to cost me first place at my first Nationals.


What is your best advice for other Drivers starting out?
Take a school, ask people for help and advice (and be receptive to it), and don’t give up! Don’t be too hard on yourself, driving skills take a long time to polish, and do come more naturally to some people. In the end, racing is really about mental preparation, confidence, and ambition composure on course.

Why do you believe women in racing is important?
I think it’s time we see a paradigm shift about the activities that women (and men) pursue. I’m all about supporting whatever healthy hobbies people find themselves interested in, and I don’t think there needs to be gender stereotypes associated with any of them. I love to see women participating in motorsports because it serves as a reminder to all that we are on the same playing field as men, and are capable of just as much. As more women enter the world of racing, I really hope it opens the door to other ladies feeling comfortable pursuing what has historically been an atypical interest. I just hear way too many women say “That’s so cool that you race, but I could never do that!” You can, and you should give it a try!!! Maybe someday, they will.

Lastly, feel free to add anything you’d like the public to know about you, your car or your racing experience!
I’ve made efforts in the Mazdaspeed (forum) community to support and encourage all members, but particularly other women, to participate in the sport of autocross. I’ve taken part in organizing four different national meets, and assured autocross was on our schedule at each one. I also made myself available to instruct at these events, and really focused on getting the women members to take part with me. I’ve gotten several of the local member’s girlfriends into the driver’s seat at autocross events as well. It has been rewarding to watch them find enjoyment from it and helping them grow into better drivers, as many have found it easier to learn from a fellow woman, than their significant other, lol.

My teammate and partner of 5 years, Clint, and I live nearly 600 miles apart. He’s been my inspiration, engineer, coach, mechanic, and best friend all along, and I credit him for bringing me to where I am today, and for building us an amazingly capable and unique car. I just started a blog to keep track of our long-distance relationship racing adventures this year, as well as driving tips, goals, and my progress through each event! www.TheRacecarRomance.com

Boosted Down the Rabbit Hole

“Intake, test pipe, and a tune ONLY” was my mantra.  I’d just bought a shiny new ’13 tech package VRM MazdaSpeed3 with the extended warranty, 3 miles on the odometer as it rolled off the lot for the test drive.  Via the web forums (back when MSF was still popular), I had performed my due diligence in terms of where I was headed with this ride. I knew what my mods would be, the results to expect, and even learned a bit about the tuning process, all with the intent to “stock out” in less than an hour in the event I broke something on the car.

But… the local Nator chapter wrapped their slithering hentai tentacles around me, and those thoughts of a mildly tuned car with the manners fully intact started to erode.  The friends, the fun, and the performance results were an instant addiction.

In just a few short months I had sold that warranty back and started down the rabbit hole.  Trips to Epic NATOR Meets were a terribly awesome influence, seeing cars on the bleeding edge of the DISI Mazdaspeed platform, and meeting several of the prominent people in the Mazda community that were so forthcoming with their knowledge.  The hook was set!

I found myself pursuing information, and if there wasn’t any data to be had, I wanted to make it myself.  I tested and cataloged a variety of items, from NVH with motor mounts to compression test compendiums (yes Cylinder 3, you deserve that BAD rap!), meanwhile moving along the mod path to a medium turbo, front mount intercooler, and a methanol kit.  Once I purchased a spare long block, I knew I was getting in ball-joints deep.

Fast forward to today.  I’ve been very fortunate to be chosen to test products for a handful of vendors!  With an aligned focus – direct fit or minimal fabrication parts – I’ve reached my (probably temporary) goal of 500 wheel horsepower! Where I’ve tested the limits of products/parts for many companies – whether they have asked me to or not. The CorkSport 3.5 Bar Map Sensor is a solid example of exceeding the envelope, as I did manage to over boost while playing with my EBCS configuration, and pegging it at 37.58 PSI. (At 900 ft. ASL)

 Corksport asked me to describe my modification journey and how their beta parts have impacted my build and decisions, so there is no slight intended to the multitude of other people involved in my project – that list is not short.

I’ve run the Corksport intake manifold for nearly 2 years and just prior to the big turbo transition.  

  • It gained 12 g/s flow on the identical tune and no other modifications, so I knew it was an immediate upgrade.
  • I’ve been hammering  30+psi through it for the majority of that time, and my built engine is approaching 25 thousand miles with that duress.  
  • The spark plugs have been pristine and uniform, indicating to me the flow is balanced in the runners.  
  • There is no better fitting upgrade intake manifold for the platform.  

The beta-testing portion of this journey has been pretty awesome. Constant emails and conversations back and forth with the CorkSport Engineering team, and support from installation, to checking in periodically afterward to see how the system is running and the part is performing for me and my particular set-up. I understand that I am not the only one to have been running this part as a beta-tester, which just shows how thorough this company is with it’s beta-testing.

Barett, the CorkSport engineer, was probably annoyed with the ‘data-whore’ aspect of who I am, but man was it fun! Tracking my progress throughout, and sending info back and forth fed the logical performance driven sides of me for quite a while.

The manifold was recently combined with the Corksport 72mm throttle body, which takes advantage of the IM’s oversized opening, which I feel will scale up with even more power should I get the itch for ludicrous speed.  There is zero loss of drivability with the TB mimicking the factory unit electronics and nothing for your tuner to battle with like the old days of trying to open up that choke point.

While it’s usually about performance parts for me, I have to say that I run a few of the CorkSport “comfort” pieces and can genuinely say they are worth the investment. The CorkSport Performance Steering Wheel is just amazing! The contoured grips are a tremendous comfort for long drives, and the beefy upper section is awesome for the twisties in roads like the “Tail of the Dragon” in NC. It’s also shown no signs of wear in the last 2 years, and I look forward to driving with it for many years to come.

I was lucky enough to get the CorkSport Hood Strut kit when they were available, and now my hood opens significantly more than the prop rod and facilitates installing those go fast bits. (Hopefully, CorkSport gets wise and brings them back for sale again).

I would like to thank Corksport for giving me the opportunity to test their parts, in addition to many others, and YOU for taking the time to read my cool story, bro!

Spread the boost – there is no vaccine!
