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 is great for your hatchback model. For more information and complete pricing, please visit our product listing page at https://www.corksport.com/corksport-power-series-exhaust-system-mazda-3.html
Product Release! CorkSport SkyActiv Mazda 3 Power Series Single Exit Exhaust March 18th, 2019CorkSport
Designed and tested for the side mount intercooler, the CorkSport intercooler hoses replace the stock rubber hose with strong, flexible, reinforced silicone that will allow for ideal flow in and out of the intercooler, provide improved throttle response, and smooth out boost pressure.
The silicone is custom formed for perfect fitment and has been designed as a direct bolt on replacement for the stock non-reinforced rubber hoses. Spurred by Mazdas recent discontinuation of the replacement cold pipe for the Mazdaspeed Protégé Intercooler, CorkSport has included both the cold pipe and hot pipe in the kit and is now the only silicone cold pipe replacement kit on the market.
“The OEM intercooler piping is prone to cracking over time which can cause hesitation and a loss of power”, said Rich Harris, President of CorkSport Mazda Performance, “Replacing the stock intercooler hoses with a better flowing kit will provide better flow capacity increasing reliability.”
The title of this blog is really the truth, but let me explain. We have done a couple blog posts on the Van Herck Mazda 3 that is competing in the Belgian Touring Car Series over the last year.
This 2010 Mazda 3 sedan, powered by a 20B 3 rotor engine started life as a plain model silver Mazda 3 sedan powered by a 1.6 diesel engine. In today’s post we will explore the evolution of the Team Van Herck Mazda 3 and how it became the machine it is today.
The process starts with several hours of stripping the car to get a chassis ready to start work.
Next they changed the drive train layout from a front wheel drive econobox to a rear wheel drive 450 hp 20B racecar. This involves some serious surgery.
The chassis was fitted to a frame rack in order to modify the front and rear chassis. A core engine was setup to get the support frames built and the transmission mounted. You can also see the beginning of the intake penned in on the card board box.
The new framework is welded into the chassis along with the roll cage for safety. There is a huge amount of time into adding the subframe and roll cage. You can see the bolt up locations for the rear diff in the bottom of the V in the cage on the right side.
With the Mazda 3 being changed to rear wheel drive it required more space for the rear tires for the 3 rotor engine. The inner wheel liners had to be built and incorporated into the new rear suspension. The upper suspension pick up points are shown just above the new rear frame.
You may not recognize the black rear differential sub frame, that is because it is from a BMW. In this case it was used for two reasons, #1 there are tons of them available, and #2 there are plenty of options available for final drive ratios.
The rear shot through the trunk really shows the extra width given to the rear wheels.
After all of the frame work was finished up the entire chassis was painted white including the roll cage. The seat was mounted along with the pedals, steering, and wiring was started.
The rear suspension links and shock absorbers were mounted up with the new hubs.
The engine bay was coated with a layer of reflective heat insulation. Critical areas like the frame rail which is next to the exit point of the exhaust for the 20b engine. If you look at the center of the picture you can see an opening in the firewall for the exhaust to travel in. The piping exhaust travels in an enclosed channel through the right side of the chassis.
You can see the tunnel for the exhaust system along the floor of the chassis on the passenger side. More of the wiring is completed for the fuse panel and engine control.
The car uses stainless steel packed Magnaflow mufflers and v-band clamps for quick release if it needs to be changed. You can see the exit path from the exhaust tunnel. Also notice there is no floor between the frame fitted yet. It will be filled in with aluminum to enclose the car with minimal weight.
In the front of the car, the factory crash bar has been hit with a hole saw to lighten it up and filled in with pipe to keep the air passing through it from being too turbulent. The crash bar now also houses the tow strap and an alternate mount point on the right side of the car. On the hood you can see the markings for the ducting and the planned vents.
The front suspension reveals more surprises if you look close. The suspension subframe is made from aluminum and not from a Mazda 3. The knuckle is also aluminum but from a front wheel drive vehicle as you can see the splines for an axle would go in the middle of the hub. What road race car wouldn’t be complete with some huge AP racing rotors and calipers.
With the engine fitted you get a good sense of how the layout of the airbox for the intake will be. The picture gives you a good shot of the peripheral port intake manifold on the CLR built 20B. The hydraulic reservoirs are pretty easy to ID which is a must in the heat of racing when you come into the pits and you need to quickly ID items under the hood.
With the partially finished airbox you can get a sense of size of the air intake that will be fed by the hood ducting when it is completed. The metal framework above the radiator is for additional coolers which were mounted later.
With the rest of the intake installed you cannot see the engine in the Mazda 3, just some sexy purpose built carbon fiber ducting. You also get a good idea of how wide the tires are on this Mazda 3. With the widebody front fenders, they are huge.
The trunk of the Mazda 3 gets the treatment too when it comes to function. There are coolers for the rear differential and the transmissions along with the remote reservoirs for the rear shocks. If you notice the coolant tank is also set opposite the driver in the chassis to help balance out the loads.
After 1 year of hard work the Mazda 3 was out for a shakedown run at the track. The irony of the door logos is worth a laugh, it definitely is a “New Mazda”
The last touches of the Mazda 3 were completed by adding the liverly from Mazda and the Garage van Herck Raceteam.
It was reported at the first event the other teams were very surprised at the speed of the rotary powered Mazda 3.
Here are some great videos of the 20B powdered Mazda 3
Special thanks to MVdesign for the video.
2012 should be a great year for the Mazda 3 and Garage van Herck

How to make a 1.6 Diesel Mazda 3 fun! February 3rd, 2012CorkSport
Designed to replace the restrictive catalyst in the stock downpipe and deliver improved exhaust flow for significant power gains, noticeable improvements in turbo response time, and reduced backpressure, CorkSport is pleased to announce a new high-flow catalyst option for their popular CorkSport Mazdaspeed 3 Downpipe.
The CorkSport Mazdaspeed 3 Downpipe is constructed from polished 3 Inch or 2.5-inch 304 stainless steel piping for lasting corrosion resistance and reduced heat transfer to the engine bay. Unlike many downpipes on the market, the CorkSport downpipe uses a unique divorced wastegate design that will reduce boost spikes and exhaust flow disturbances due to waste-gate operation.
The new catted version of the CorkSport Mazdaspeed 3 Downpipe provides gains of up to 21 WHP and includes a high-flow spun metallic 200 cell catalyst and three O2 bungs to allow for the addition of EGT or other sensors.
Our new catted downpipe option incorporates all of the popular features of our current Mazdaspeed 3 downpipe with the addition of the high-flow metallic flexible catalyst for cleaner emissions. We have included our popular CorkSport Mazdaspeed 3 Racepipe in the catted option to provide even more horsepower and torque to your exhaust set-up.
The CorkSport Mazdaspeed 3 Catted Downpipe is a direct bolt-on replacement for the restrictive factory downpipe and attaches seamlessly to the factory or an aftermarket cat-back exhaust set-up using a factory-style donut.
In addition, we’ve added the modular bellmouth to the design. This development provides a vast improvement during installation. The fitment is so much better with a modular v-band-connected bell mouth. You no longer need to fight the downpipe while trying to tighten it to the turbo!
The CorkSport Sponsored 2010 Mazda 3, driven by Josh Mackey, photographer and marketing specialist by day and Editor and Chief of NWMotiv.com by night, has gotten a lot of attention lately (including a feature in the December issue of Import Tuner Magazine), and for good reason. Mackey started his 2010 Mazda 3i Sedan project in June of last year with the goal of taking the mid-range sport compact car to the next level using a variety of styles and showcasing realistic modifications that anyone could do while maintaining a practical everyday car.
Josh was attracted to the Mazda 3 because of the loyal community and followers, the price point and the suspension that, even from the factory, was sportier and more fun than anything else he had test driven. Even so, he immediately set to work improving the suspension of the 3 by adding a CorkSport Front Strut Bar, CorkSport Lower Rear Sway Bar, and Stance USA GR+ Coilovers. He also replaced the tires and wheels with Konig Lace 18×8” +35 wheels and Hankook V12 215/40/18 Tires.
Mackey went with the 2.0 liter base model Mazda 3 so that he could design the car from the ground up by starting with the most common package that the everyday tuner might select, so when it came time to upgrade the engine and exhaust, Josh knew to get the vehicle to the next level he would need the trifecta of I/H/E (Intake, Header, and Exhaust).
Once the Mazda 3’s suspension and basic engine modifications were complete, adding the proper equipment to stop it was a no brainer so Josh went to work on some brake modifications with the CorkSport Stainless Brake Lines, EBC 3GD Zinc Coated Slotted Rotors, EBC Red Stuff Brake Pads and Motul Brake Fluid.
A fan of clean lines, Josh has also done some tasteful exterior modifications that include a 3M 1080 Carbon Wrapped Roof, V-LED Platinum LED bulbs and V-HID lighting, a CorkSport Front Plate Relocation Kit, Mazda Accessory Side Skirts and a 35% Matching front and rear tint.
Continuing with the same exterior design, Mackey wanted to make a point by taking his interior to a whole new level with a full leather installation provided by Katzkin Leather. Two-tone leather interior combining dark midnight grey leather that is stitched together with dark slate perforated suede is installed in both the front and rear seats and the door cards. Stage 2.0 of the build will focus on finishing the rest of the interior by wrapping the headliner and pillars in the same material. The rest of the interior is accented with 3M carbon wrap installed by Graphix by Tex and soon-to-be-installed SRP Racing two-tone aluminum racing pedals.
This particular Mazda 3 did not come with the aftermarket BOSE system that most Mazda’s get from the factory. Mackey knew that if he wanted to take this project to the next level and maintain a competitive level with other Mazda’s in the industry, a completely new audio system would be needed. Diamond Audio provided a complete setup of front and rear component speakers, amps, and low-profile subwoofer. The entire system was expertly installed by James Anderson, all controlled by an Alpine In-Dash DVD/GPS Head unit.
What’s next for the NWmotiv Project 3? “Lots of tiny little things that need to be finished up, new bumper lenses, new wheels, front lip, maybe a dptune ecu upgrade” said Mackey “The NWMotiv Project3 takes everything that I’ve learned from the years. Clean lines, clean mods, nothing overdone, and everything tasteful.”
