Description
Designed for the BMW F97 X3 M / F98 X4 M, the WERKE 3.5″ Midpipe replaces the restrictive factory midpipe with a straight-through, TIG-welded T304 stainless steel upgrade engineered for improved flow, reduced backpressure and a deeper, more purposeful exhaust note.
The high-flow 3.5″ design enhances exhaust velocity and turbo response, helping the S58 engine breathe more efficiently under both spirited street driving and demanding track conditions. Built to handle high heat and sustained load, each unit is crafted from premium materials and tested in Australia to ensure long-term reliability and precise fitment.
This midpipe includes all required installation hardware along with a replacement stiffening brace to maintain chassis rigidity and correct exhaust alignment once installed.
