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.
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.
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.
Staged Dyno Results for 2010 MazdaSpeed3 February 21st, 2018CorkSport
I just 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! Can’t wait to see what it picks up with the downpipe.
If you have a Mazdaspeed3 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.
Now I know what you may be thinking – WHAT? We don’t need any stinking catalysts. But ya see, that’s the rub – those track days at the ‘ring are lots of fun, but you’re not fooling anyone when the people in the lunch line at Laguna Seca can smell your exhaust. I’ll be the first to say that catalysts serve a great purpose and beyond the evils of over-restrictive cats on stock vehicles, can be a great addition to any performance vehicle.
At CorkSport we have been listening to you, our customers, and there seems to be an interest to have the performance of a racepipe without the foul, eye-scorching smell of fuel every time you cold start the vehicle. Well, you’re in luck – we’ve recently found a source for high quality metallic substrate catalysts in a compact yet high flowing 410 stainless steel package and we plan on offering a range of products that provide these catalysts as a configurable option with our current line of racepipes.
Catalysts: How they work and their failure modes.
A catalytic converter is a device resembles a muffler or resonator – basically an enlarged section of your exhaust system that has a honeycomb structure held inside of it. The honeycomb is then coated with a substrate that creates a chemical reaction based on heat and any unburnt fuel in your exhaust system. Anyone who has used a propane space heater – the kind that glow and don’t really give off any tangible flame – has seen a catalyst at work. Substrate and brick/insert design is relatively straightforward – the more surface area you have, the more efficient the catalyst is at burning unburnt fuel. In the search for more surface area, the density of the honeycomb increases – as does restriction of the system.
This honeycomb comes in two forms – a metallic stainless foil version and a ceramic version. Based on the manufacturing process, the ceramic version must be retained in the canister with a fiberglass or vermiculite packing material around the circumference of the ceramic ‘brick’. In rotary and turbocharged applications, this material often deteriorates from excess heat and pressure allowing the ceramic substrate to rotate and/or crack.
Our catalysts
Our catalysts utilize a 200 cell metallic substrate design and have the honeycomb material all the way to the wall of the canister without any additional packing material that may deteriorate. The metallic spiral is held in place mechanically from either end to prevent movement. The canisters and tubing are made of 410 Stainless Steel and all carry a 5 year manufacturers warranty.
New products
To start with we will be offering the RX-8 Power Series Racepipe in a single resonator/single 65mm catalyst configuration (as well as a single or dual resonator configuration). We’re in the process of doing the first production run on these and hope to have them out in the next two or three weeks.
The next product we will be working with is the Mazdaspeed3 Racepipe with 80mm high flow catalyst, this should be available in the next month in production quantities.
Finally, we are also working on Mazdaspeed6 Racepipe with 80mm high flow catalyst.
Drop me an email if you’re interested in getting in on these products hot off the mandrel – we’ll have a handful of pre-tested prototypes and then full production runs of all of these products within the coming months.
The last week has been a lot of fun here at Corksport. We have been working on developing a cure for High Decibel Situational Tourettes Syndrome, which effects a certain percentage of enthusiasts who run a non resonated racepipe in their RX-8.
Our latest solution is a dual resonated Power Series Racepipe for the ’04-’10 RX-8. Incorporating a 140mm primary resonator and a 100mm secondary resonator with 61mm exhaust tubing, the resonated racepipe improves exhaust flow dramatically while keeping the decibels at a level reasonable enough to avoid spontaneous profanity from drivers and spectators alike. Think your racepipe is too loud? Check out this video clip of the Power Series Dual Resonated Racepipe and with Power Series Cat-Back Exhaust on our ’04 RX-8 and let us know what you think:
Like all of our Power Series exhaust products, the Dual Resonated Racepipe for the RX-8 incorporates only the highest quality materials and manufacturing methods. Featuring T304 stainless mandrel bent tubing, stainless oxygen sensor fittings (one for the stock oxygen sensor and a secondary unit for the use of a Wideband O2 monitoring & datalogging system), T304 resonators and flanges. All connections are TIG welded with 308 stainless rod to ensure good weld penetration and attractive finish on the weld bead. We’re hoping to get a handful of these systems out on the street in the next month and we’ll keep you posted as soon as they’re available to the public.
We’re also entertaining the possibility of incorporating a high flow catalyst into the system to keep emissions to a minimum. This will be a 108mm spun metallic substrate catalyst replacing the secondary resonator. If this is something that would interest you, let me know by dropping me an email.
Next week: Short Ram Intake Cold Air Box Performance Results & Analysis for the Mazdaspeed 3 and 6.
