Description
Constructed with 304 stainless steel tubing, this system offers a significant weight savings of 12 lbs compared to the stock exhaust. It features a new GP19 style canister with a black ceramic coating. The system includes a pre-installed Stage 1 Q1 quiet insert and is designed to remove the catalytic converter, with an included O2 bung that accommodates both M18 and M12 sizes. It allows for valve removal, contributing to improved exhaust flow and sound. The stock system produces 95 dB at 7,000 RPM, while the M4 system increases this to 112 dB at 7,000 RPM.
