Are you wanting something for your Mazda 3 to give it a whole new feeling and presence when you’re carving the backroads or just driving on your daily commute? The CorkSport 80mm Cat back Exhaust does just that, all while being virtually drone free so highway cruising and driving around town is still enjoyable.

The 80mm CBE is the ultimate exhaust for those who want the best sound and performance out of your Mazda. The tone is more aggressive than the CS 63.5mm CBE, but refined at the same time giving it the best of both worlds. Check out the sound clips below to listen to what your Mazda will sound like with the CS 80mm Cat Back Exhaust (Coming Soon).

The 80mm cat back was optimized for the SkyActiv-G Turbo engine, but will also fit the AWD non-Turbo models if you are wanting a louder more aggressive exhaust tone.

The CorkSport Advantage

Best Mazda 3 Turbo Cat Back  3-inch Exhaust

Optimized Sound:

The CorkSport 80mm Catback Exhaust was designed specifically for the 2.5L SkyActiv-G Turbo engine as a complete cat back with unique dual chamber resonators. Because of this, the 80mm exhaust will only be sold as a cat back.

When increasing the piping diameter, commonly more drone is created which is annoying to drive with. We developed the dual chamber resonator specifically for this engine to combat drone in both high and low frequencies.

  • While retaining the same unique asymmetrical axle back design; we went through multiple resonator setups and this combo proved to offer the best sound with the least drone so you can enjoy the best of both worlds while driving.

    Horsepower Gains:

    The Cat Back has a noticeable power increase after installation. While we wait on our AWD dyno to arrive, on-street testing has shown improvements in airflow and response when switching from the OEM exhaust to the CS 80mm Cat Back on a Mazda 3 Turbo model. After installing, there is no tuning required for your Mazda. Depending on your mods, you may achieve a higher power potential.

    OEM Fitment:

    Fitment was a major part of the development of the CorkSport 80mm CBE. We went to great lengths to ensure that the fitment matched the OEM quality so the installation is spot on. We checked fitment with the stock hatch bumper, appearance kit bumper, and sedan to ensure all setups look and fit as good as the CS 80mm CBE should.

    To provide great ground clearance and ample room for the drive shaft, the exhaust was tailored fit to the vehicle.

    2021+ Mazda 3 Turbo 80mm Exhaust material

    Materials & Manufacturing:

    The CorkSport 80mm CBE is constructed from 304 stainless steel, mandrel bent, and TIG welded. The Cat Back is then fully polished to provide a great look. We have reinforced the hangers with extra support to make sure they will withstand harsh driving conditions.

    2019-2023 Mazda3 Installation Instructions for a hatch Wing

    10/10 sound. not too loud not too quite. 10/10 welds. reason i’m giving a 3 star is because the fitment was off. followed the instructions and aligned the flanges and gaskets perfectly but the exhaust ending up rubbing on the driveshaft and taking some paint off. i had to readjust the exhaust by pulling it away from the driveshaft and retightening all the bolts down. everything is good now but now i gotta repaint my driveshaft before it gets some rust. other than that well built exhaust and solid sound.
    Love my exhaust! Fit requires careful following of instructions, will rub the drive shaft if not mounted properly. Performance and sound is AMAZING! Sounds like a proper performance vehicle instead of a quiet little sleepy thing. There is some drone cruising at highway speeds, but it's minimal.
    WOW! Yet another great CS product! These guys nailed it on the sound, performance gain, and ease of installation. It was worth the wait. The sound is deep and tough! No drone inside the cabin but you can definitely hear the growl!
    Nice, well mannered exhaust that sounds better the more you drive it.
    What's that? I can't hear you over my luxury sport plus mods. the added sound really defines the spirit of this car, no annoying drone and all bark. Inside the cabin is pleasant and the sounds of the intake and exhaust have me driving on the low end of my fuel economy. Fit and Finish are top notch as usual from a CS product
