HM S68 Midpipe - G90 M5

The HM S68 Midpipe is precision engineered for the 2025+ BMW G90 M5, designed to enhance both sound and performance while maintaining OEM fitment and quality. Constructed from high-grade 304 stainless steel, this system replaces the restrictive factory midsection with a 76 mm (3.0 in) mandrel-bent design that improves exhaust flow, reduces backpressure, and delivers a deeper, sharper tone from the S68 hybrid twin-turbo V8. A custom-formed heat shield is integrated around the front section where the midpipe connects to the downpipes. This helps protect nearby components and reduce tunnel temperatures, especially during high-performance driving or extended operation in warmer conditions. Each HM S68 Midpipe is a direct bolt-on replacement using factory-style flanges and hangers, and it includes all necessary hardware for an easy, no-weld installation.
