The COBB 3" SS Catback Exhaust was engineered specifically to match the performance needs of the 2007-2009 MAZDASPEED3. The attention to detail that goes into the fabrication of this catback makes it a shame to hide it underneath the car. Manufactured using mandrel-bent T304 stainless steel with a custom resonator and high-flow muffler for optimal performance and reliability. Its factory-like fit, attractive finish and subtle yet deep exhaust note put it safely 11 dB below the SAE J1169 limit.
The COBB Tuning Gen1 MAZDASPEED3 Cat-Back is constructed purely from 304 Stainless Steel. The system starts with a stock donut-style flange that mounts to the OEM downpipe or any stock-replacement downpipe, such as the COBB Tuning 3" Downpipe.
Next up is a polished resonator section with attractive rolled end-cap, followed by a polished low-restriction straight-through muffler section, also with this attractive rolled end-caps. A thick stainless-steel 2-bolt flange connects to the final section of the exhaust that ends in a tasteful, slash-cut 3.5" double wall tip featuring an etched COBB logo.
