CorkSport | Cat-Back Exhaust 80mm - Mazda 3 SEDAN 2014-2018

CorkSport - 2014-2018 Mazda 3 80mm Cat-Back Exhaust

Performance Sound

The sound is the truly unique feature of the CorkSport 80mm Cat Back Exhaust. The 80mm piping really lets the SkyActiv-G engine sing, even more so than the CorkSport 60.5mm variant. The increase in volume also comes with some fantastic & unique tones that make hitting a curvy road exciting. We didn’t just copy the original 60.5mm design though and make the pipes bigger, we went through multiple resonator designs to get the best sound without ruining the drivability of the Mazda 3.

Adding Power & Room for future Mods

By replacing the restrictive stock exhaust with large-diameter mandrel bent piping and high-flowing resonators, we are able to gain some much-needed horsepower. When compared back to back with an OEM exhaust, the CorkSport 80mm made 5-7WHP. No tuning or part changes other than the exhaust swap. This will pair well with future GEN3 parts in the works that will probably need that extra volume for optimal power. And whoever said planning ahead was a bad thing?

Style Boost

The aggressive sound comes with an aggressive look to match. Each exhaust tip has been enlarged to 100mm (just under 4”). For the hatchback, these tips are dual wall & slant cut to match the bumper shape and fill out the cutouts. For the sedan, single wall tips are used to ensure water and debris don’t build up in the turn-down. In each case, the exhaust accents the rear of the car to give an aftermarket look that is stylish and the way it should have come from Mazda.

High Quality Materials & Manufacturing

Each exhaust is made from fully polished T-304 stainless steel that is TIG welded together. This combo makes for a great-looking exhaust that will last as long as your Mazda. All the flanges are laser cut for consistency and 9mm (~3/8”) thick to prevent warping. This package is wrapped up with high-strength hardware, full-color install instructions, and all the gaskets you need for a painless install.
