Description
The WERKE 3.5″ Midpipe for BMW G80, G81 and G82 M3/M4 is a TIG-welded T304 stainless steel upgrade that replaces the restrictive factory dual midpipes with a single high-flow 3.5″ unit. Designed to reduce weight and increase exhaust flow, it unlocks a more aggressive exhaust note and sharper response from the S58 engine.
By consolidating the factory dual system into a single 3.5″ midpipe, this upgrade improves exhaust velocity, reduces backpressure and enhances turbo spool, delivering a more engaging driving experience both on the street and at the track. Engineered and tested to handle high-heat, high-boost conditions, the WERKE midpipe is built for serious performance and long-term reliability.
Each system is supplied with all required mounting hardware and a replacement stiffening brace to maintain chassis rigidity and correct exhaust alignment after installation.
