Stainless Steel Cat-Back Exhaust System

The Cobb Tuning Catback Exhaust is a direct-fit, mandrel-bent 304 stainless steel system engineered for the 2007-2009 Mazda Mazdaspeed3 with the MZR DISI 2.3T engine and manual transmission (Gen 1). Constructed from durable 304 stainless steel, the system features TIG-welding throughout for maximum strength and longevity. The mandrel-bent tubing maintains a consistent diameter, eliminating the flow restrictions often found in crush-bent pipes and ensuring smooth passage for exhaust gases. This design contributes to both performance gains and a corrosion-resistant finish that withstands the rigors of daily driving and performance use. This cat-back exhaust is specifically tuned for the Gen 1 Mazdaspeed3, ensuring correct hanger positions and routing for a seamless installation. It aims to provide an improved sound character over the factory exhaust, offering a more purposeful tone without the undesirable drone often associated with aftermarket systems. All necessary installation hardware, including hangers and gaskets, is included to facilitate a straightforward bolt-on process. Cobb Tuning's commitment to developing integrated performance systems is evident in this cat-back exhaust. It is designed to complement other performance modifications such as the Cobb Accessport calibration and SF intake, completing a package that allows the 2.3T engine to perform noticeably beyond its factory specifications. The 4-inch polished tip adds a subtle aesthetic enhancement to the rear of the vehicle.
