Product Details

Transform your BMW G20 330 from a muted daily commuter into a track-inspired performance machine with the Turner Motorsport Valved Cat-Back Exhaust System. Designed for enthusiasts who demand zero compromises between refined streetability and an aggressive tone, this cat-back system maximizes exhaust flow while giving you complete control over your vehicle's voice. Built from heavy-duty 80mm mandrel-bent 304 stainless steel piping, it minimizes backpressure to help your engine breathe freely.

Unlike the factory muffler design that restricts exhaust flow to a single exit when closed, Turner’s engineered high-flow valved muffler utilizes both exit pipes in both valve-open and valve-closed modes. This intelligent dual-path layout delivers unrestricted flow and a rich exhaust note regardless of valve position. Finished off with signature Turner engraved polished tips, this system delivers the track-tested acoustic presence and bold aesthetic your BMW deserves.

80mm mandrel-bent 304SS pipe
High flow, valved, stainless steel muffler
