Description
Upgrade your Duramax diesel truck with the CORSA Sport 4.0" Diesel Muffler Upgrade Kit, engineered to reduce drone while enhancing performance and sound. Designed for Chevrolet and GMC Duramax engines (6.2L, 6.5L, and 6.6L), this muffler increases airflow and improves exhaust tone without compromising durability.
Constructed from premium 304 stainless steel, the round muffler features a 4.0" expanded inlet and outlet with clamps, a center inlet location, and a single 4.0" outlet. The 23.25" case length and 9.62" case diameter ensure optimal fit and airflow. CORSA’s proprietary design mitigates most drone-inducing frequencies for a smoother driving experience.
