Product Details

Let's be honest—what's the point of owning a B58-equipped BMW if you can't hear it? The F30 340i and F32/F33 440i feature a bulky, suitcase-style rear muffler assembly that muzzles the B58's turbocharged symphony. While cat-back exhaust systems can be a serious investment, our new muffler delete kit offers a cost-effective alternative that delivers all the sound, style, and performance your BMW deserves.

Our system completely transforms the character of your F3X by replacing the restrictive rear muffler with a high-flowing, TIG-welded stainless steel setup that enhances tone, reduces weight, and maintains factory fitment and finish. The Turner Motorsport Muffler Delete Kit features dual 80mm primary tubing that transitions to adjustable 100mm tip sections for a clean yet aggressive look. Up front, the muffler delete kit attaches to the OEM mid-pipe using factory-style sleeve clamps. The connecting pipe is installed at a factory cut location, creating an easy and reversible modification. At the rear, the included sleeve clamps enable easy adjustment and precise tip placement inside the factory rear diffuser.

Features & Benefits:

TIG-welded dual 80mm primary tubing seamlessly transitions to adjustable, twin slash-cut 100mm tip sections, delivering a bold, refined appearance
Straightforward cut-and-clamp installation, 100% reversible
Sleeve clamps provide full adjustability for effortless alignment and precise tip positioning
Utilizes factory exhaust hangers for a clean, bolt-on installation—no cutting or drilling required
