3-Inch Catted Stainless Steel Street Downpipe

The COBB Tuning 571202 is a 3-inch stainless steel street downpipe specifically designed for the Mazdaspeed 3. This downpipe is a key upgrade for unleashing the hidden torque within the MZR 2.3 DISI Turbo engine. It features a catted design and is constructed from durable stainless steel for longevity and performance. This beautifully fabricated downpipe significantly improves exhaust flow, directly translating to a faster turbo response time and noticeable power gains across the entire rev range. It is designed to work with the stock cat-back exhaust system, tapering to 2.5 inches near the end to ensure compatibility. Installation of this downpipe will require custom tuning or utilizing an appropriate COBB Stage Power Package map to maximize its benefits and ensure optimal engine performance. While it can be installed without an Accessport, an Accessport is necessary to achieve the full performance potential and any associated gains.
