Turner Motorsport G2X M340i/M440i Muffler Delete Kit

Let's be honest—what's the point of owning a B58-equipped BMW if you can't hear it? The M340i and M440i both feature a bulky, suitcase-style rear muffler assembly that silences a wonderful exhaust note that the B58 was born to deliver. While full cat-back exhaust systems can be a serious investment, Turner Motorsport’s new muffler delete design offers an affordable alternative that delivers all the sound, style, and performance your B58 deserves. 

This system completely transforms your BMW's character by replacing the restrictive rear muffler assembly with a high-flow, TIG-welded stainless steel setup that enhances tone, reduces weight, and maintains factory fitment and finish. The Turner Motorsport Muffler Delete features 3" primary tubing that transitions to dual 2.5" adjustable tip sections for a clean yet aggressive look. Accuseal-style slip-fit joints allow for easy adjustment and perfect tip placement inside the factory rear diffuser. Quad 2.5" tailpipes offer compatibility with your choice of Turner Motorsport exhaust tips.
