The best looking, sounding, and performing exhaust for the Mazdaspeed 3. You have come to the right place if you want the best. Using the best materials in construction, providing the best dyno performance, including the best step by step instructions, and the best customer service, it's easy to see that we are not exaggerating.
New Options! You can choose the optional non-resonated rear version of our cat back to take the sound level up a notch. We made this option available due to customer feedback of those wanting a turbo back which captures the Mazdaspeed 3s flat exhaust note.
The CorkSport exhaust features mandrel bent 80mm piping, a straight through high flow muffler for a smooth flow, increased power, and faster spool up. Plus with the included high-flow catalytic converter you get all the power while preventing CEL lights and over-boosting conditions. Corrosion-resistant T304 polished Stainless Steel construction with 100mm stainless steel tips ensures long life; stainless steel resonator packing means no worrying about burning out and rattling. As with all of our CorkSport exhausts, the Turbo Back exhaust is precision TIG welded, making for a solid connection, cleaner look, and powerful presence.
