Let’s be honest—what’s the point of owning a B58-powered BMW if you can’t hear it? The factory M340i and M440i rear muffler assembly is oversized, heavy, and overly restrictive, muting the deep, aggressive tone the B58 engine was designed to produce. Our Muffler Delete System is the perfect solution for enthusiasts looking to unleash that signature turbocharged inline-six sound without the cost of a full cat-back system.
Engineered and manufactured in-house, this system replaces the factory rear muffler with a free-flowing, TIG-welded 304 stainless steel setup designed to enhance tone, reduce weight, and maintain OE-level fitment and quality. At the front, 3" primary tubing mates seamlessly to your factory midpipe using a durable stainless steel sleeve clamp. At the rear axle, the primary tubing transitions to dual 2.5" adjustable tailpipe sections for a clean, yet aggressive look. These tailpipe sections merge to quad outlets, designed for compatibility with our selection of 3.5" exhaust tips, allowing you to tailor the system's appearance to your liking. Accuseal-style, slip-fit joints allow for easy adjustment, ensuring perfect tip placement inside the factory rear diffuser. The result? A more engaging exhaust note and a clean, motorsport-inspired appearance that transforms your BMW’s personality both visually and acoustically.
