Introducing the CorkSport Cat Back Exhaust for 2019+ Mazda 3. Add some much needed sound to the 4th GEN 3 and improve performance! The CS cat back exhaust replaces everything from the header back with 63.5mm fully polished, mandrel bent, stainless steel piping. It's a step up in volume and aggressiveness from the CorkSport axle back exhaust, without adding annoying drone or raspy tones.
Sound Boost:
The CorkSport cat back exhaust completely replaces the OEM midpipes and restrictive OEM muffler section with 63.5mm mandrel bent pipe and pass-thru resonators. The larger pipe adds a great sound and tone for the backroads while the high flowing resonators control drone so your car is still comfortable on the daily commute! We tested multiple resonator setups in both the axle back and midpipe sections and found that the asymmetric axle back design and large oval resonator in the midpipe results in the absolute best combination of tone, volume, and drone control for your MZ3.
Horsepower Gains - Non-Turbo:
What good is sound without a little power to go with it? Installing the CorkSport Cat-Back Exhaust (with the CorkSport Short Ram Intake previously installed) netted us approximately 20wTQ and 10-18wHP. You can see significant gains from 2700rpm through the rpm range til redline at 6200rpm. Note: AWD Turbo model has not been tested.
OEM Fitment:
Each CS cat back exhaust system was designed from the ground up to fit just like your OEM exhaust system. We offer two different midpipe setups for great fitment, no matter if your vehicle is AWD or FWD. Don’t worry though, both use the same resonator design so you know your car will sound great, regardless of your drivetrain!
Cylinder Deactivation:
If your Mazda 3 is equipped with cylinder deactivation don’t be worried because we have a solution for you. Utilizing a bracket made out of 304 stainless steel, you can mount your cylinder deactivation motor securely out of the way to ensure no check engine lights are set and also reduce the restriction caused by the factory internal valve.
Personalized Appearance:
The CS catback exhaust system comes with your choice of exhaust tip option. We have fitments for the hatch, sedan, and even the hatch with the aero kit! The aero kit option is simply a more aggressive hatch fitment that goes perfect with the more aggressive OEM Mazda aero kit. If you want a more subdued look, the regular hatch fitment also looks great. To top it off, each tip fitment can be adjusted outward to suit exactly the look you are going for on your Mazda!
Materials & Manufacturing:
The CorkSport cat back exhaust is made from fully polished, mandrel bent, 304 stainless steel for a fantastic look that will stand up to the elements and keep your Mazda breathing easy. All joints use TIG welds for long lasting strength and all hanger locations have extra bracing to ensure a secure exhaust for years to come. Lastly, each exhaust comes with all hardware and gaskets that are needed for install to keep your install day running smoothly!
