Open up your Mazda 6 Turbo with the CorkSport Cat Back Exhaust.
Add to wish list

We are proud to introduce the CorkSport Cat Back Exhaust for 2018+ Mazda 6 equipped with the 2.5L Turbocharged engine. With the first turbocharged Mazda 6 to come to the USA since 2007, Mazda did a little too well at quieting down the SkyActiv 2.5T.

The CorkSport cat back uses fully polished 80mm piping and pass through resonators to wake up your Mazda6, adding both sound and power.5-6WHP to be precise, with no tuning changes & the only other mod being the CorkSport SRI.

Check out the video below for sound clips and the information below that for full details.

Go With The Flow

The CorkSport Cat Back exhaust replaces the ~60mm OEM exhaust with 80mm piping, an increase of over ¾”. This increases the peak flow of the exhaust to allow for extra power. The OEM exhaust also includes crushed sections, a secondary catalyst, and a restrictive muffler section, all of which adversely affect flow. The CorkSport exhaust however, uses all CNC mandrel bent piping and flow through resonators to give your 2.5T the best combination of power and sound.

Bolt On Power

The graph below shows gains of 5-6WHP with no tuning or other part changes. The only other modification to the vehicle was a CorkSport SRI, which was installed for both runs. Your Mazda 6 can have these gains without the worry of a CEL with a simple bolt-on installation that only takes a few hours. Plus, the exhaust is ready to support any future mods you want to throw at it.

Performance Sound

The added flow and larger piping ups the volume on the MZ6 without adding drone. We went through multiple iterations and resonator combinations to find the best combination of tone and volume. We strongly recommend you watch the video above to hear how great the CS exhaust sounds

Classy Styling

Each CorkSport exhaust is made from fully polished stainless steel for a great look that will last. To enhance the beautiful styling of the Mazda 6, the exhaust tips were increased in size and brought rearward slightly. These dual wall 100mm tips fill out the bumper for a sleek look that lets you know something is different without being obnoxious. Lastly, they are finished off with a laser engraved CorkSport name badge for subtle detail.

Precision Welded

Each exhaust is precision TIG welded together for a strong, well-fitting system. The OEM hanger locations are used to keep the exhaust in place with no concern for hanging too low or rubbing on underbody components. In addition, the manufacturing jigs were made from OEM exhaust components to ensure a great fit for every Mazda 6 owner.

Mazda 6 Turbo Exhaust Installation

Very nice look and fit, to me the sound is exactly what I wanted, low down rumble that doesn’t reverb or drone inside the car.
Very tidy work
Found a 2020 with 4k miles and this exhaust in a dealer showroom. I bought as soon as I heard it start. The whole dealership rumbled! Wife asked me if I could "turn down my engine". Uh, no
Too loud for me. Was hoping for more tone than overpowering exhaust noise. Beware if you live in cold areas, will wake up neighbors and shake house windows. Hoping for a axleback soon. Ended up selling mine. If you are wanting a loud exhaust with great tone, this is the one for you.
Love it. Sounds great in combination with the CS intake under the hood. Nice and deep sounding for a 4 cylinder with the perfect decibel level at WOT. I'm impressed.
Its a little loud on startup but mellows out quickly. The bigger tips look great.
