Why own the only V8-powered M3 if you can’t actually hear it? BMW's E9X M3 features a hefty rear muffler assembly that silences the S65's distinctive soundtrack. While full cat-back systems can require a serious financial commitment, our new Muffler Delete Kit offers an affordable, no-compromise solution that brings your M3 to life!

This system transforms the character of your S65 by replacing the restrictive factory mufflers with a free-flowing, TIG-welded stainless steel assembly designed to amplify tone, shed weight, and preserve OEM fit and finish. Our design features dual 2.5" primary tubing that flows into adjustable 3" quad tips, creating a clean yet aggressive aesthetic. Up front, factory-style V-band flanges connect directly to the OEM midpipe—meaning no cutting of factory exhaust piping. At the rear, Accuseal slip-fit connections allow perfect tip alignment within the factory diffuser, ensuring a tailored, symmetrical look every time.

The Race Series muffler is meticulously designed for uncompromising performance, delivering an aggressive racecar-inspired sound. Its genuine straight-through design ensures the utmost high RPM power, while the 2.5" or 3" perforated core effectively eliminates backpressure, optimizing exhaust flow.

This muffler stands as the ideal choice for dedicated racers, turbocharged engines, nitrous oxide fuel systems, or vehicles equipped with wild cam applications. It boasts a 2.25" inlet, a 24" overall length, and a 4" diameter round, angle-cut tip.
