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.
FEATURES
TIG-welded dual 2.5" primary tubing transitioning into adjustable 3" quad tips for a bold, refined appearance
OE-style V-band flanges for true factory-like integration—no cutting required
Accuseal slip-fit joints for full adjustability and precise tip placement
Utilizes factory hangers for a clean, bolt-on installation with zero drilling or modification
