Overview

The Cobb SS 3" Cat-Back Exhaust is a performance exhaust system designed to minimize back pressure and maximize power gains. Its layout features a 3" diameter pipe that splits into dual 2.5" pipes, leading to dual 4" slash-cut tips.

Constructed from T304 stainless steel, this exhaust system offers durability and corrosion resistance. It includes one primary and one secondary resonator to subdue harsh engine noise while maintaining a mellow, powerful rumble. The system is designed to meet the 95dB sound restriction.

This cat-back exhaust is compatible with the stock or any direct factory replacement downpipe and includes all necessary gaskets and hardware.
Show original supplier description
The Cobb SS 3" Cat-Back Exhaust is engineered for the 2010-2013 Mazda Mazdaspeed3, featuring an optimized layout with minimized bend degrees in the exhaust piping to reduce back pressure and enhance power. The 3" diameter piping transitions to dual 2.5" piping for efficient exhaust flow, and the system tucks close to the undercarriage for maximum ground clearance. Constructed entirely from T304 stainless steel, this exhaust system ensures long-lasting durability and corrosion resistance. The exhaust system is engineered to meet the SAE J1169 sound restriction of 95dB, even when used with a full turbo-back system. The system is finished with dual 4" slash-cut, double-walled rolled tips featuring laser-etched COBB logos. All necessary gaskets and hardware are included, utilizing the stock doughnut gasket for connection to the downpipe. While designed for the 2010-2013 Mazda Mazdaspeed3, it is important to note shipping restrictions. This product cannot be shipped to Australia, the UK, or California due to vendor restrictions. Additionally, international shipping outside of the United States is not available.
