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 from those wanting a turbo back that captures the Mazdaspeed 3's flat exhaust note.

The CorkSport exhaust features mandrel bent 80mm piping, a straight through high flow resonator for a smooth flow, increased power, and faster spool up. 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.

Thoroughly tested, this exhaust has peak power gains on the dyno with increases up to 50 wheel horsepower over stock with the needed supporting parts (Max Flow Fuel Pump, Intake and Accessport.)
