Corksport | Cat Back Exhaust System 63.5mm - Mazda 3 AWD SEDAN 2021+

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.

The CorkSport Advantage

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.

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.
