MAZDASPEED3 GEN2 SS 3" CAT-BACK EXHAUST

The COBB 3" Stainless Steel Cat-Back Exhaust is engineered to deliver optimized performance, aggressive sound, and clean aesthetics for your turbocharged setup. With a routing layout designed to minimize total bend degrees, this system reduces back pressure and enhances exhaust flow from the downpipe all the way to the tailpipes. Constructed entirely from T304 stainless steel, it features a 3" main pipe that splits into dual 2.5" rear exits, ensuring the ideal path of least resistance. Harsh engine tones are mellowed by a primary and secondary chambered resonator, keeping the sound deep and throaty without overwhelming volume—perfectly legal under SAE 95dB regulations. Designed to stay tight against the undercarriage, this cat-back ensures maximum ground clearance, even for lowered vehicles. The custom-built resonators, satin-finished tubing, and twin 4" double-wall tips give it a striking finish that complements its performance. This system installs cleanly using two-bolt flanges with
