The COBB Tuning 3" SS Catback Exhaust was engineered specifically to match the performance needs of the 2010-2013 MAZDASPEED3. Full description
The layout of this COBB 3" SS Cat-back was chosen to minimize the total bend degrees used to route the exhaust piping for reduced back pressure. The entire system fits within the factory exhaust path to allow the exhaust to be tucked up as close to the undercarriage as possible to achieve maximum ground clearance. Exhaust piping is 3" diameter from the downpipe to the split, where dual 2.5" pipes whisk the exhaust out of the system. The resulting path of least resistance minimizes back-pressure for maximum power gains. Harsh engine exhaust noise is subdued via one primary resonator and one secondary resonator. These chambered resonators provide sound reduction without adding restriction to the exhaust flow. The resulting mellow rumble sounds and feels powerful, without being overbearing. This exhaust was designed to meet the 95dB sound restriction even when used as part of a full turbo-back exhaust system. Significant effort went into making this exhaust look as good as it sounds and performs. Both resonators are custom built and finished with beautiful welds. The 2.5" and 3" stainless steel piping has a satin finish for a stunning appearance. The exhaust is finished with two 4" slash-cut, double-wall rolled tips with laser etched COBB logos. The entire kit is constructed of T304 stainless steel to ensure that it stays looking this great for years to come. This cat-back exhaust will work with the stock or any direct factory replacement downpipe. The two bolt flanges allow slight adjustability for absolutely perfect fitment. Includes all gaskets and hardware, and uses the stock doughnut gasket to mate to the downpipe.
2.MazdaSpeed3/Axela/3 MPS 2010-2013 3" Cat-Back Exhaust - 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.
