Improve exhaust flow and enhance exhaust tone on your 2017-2023 BMW 550i G30/G31 with an HPH Midpipe, engineered to reduce restriction in the center section of the exhaust system.
The Midpipe replaces the restrictive factory mid-section, allowing exhaust gases from the 4.4-liter twin-turbo N63 V8 engine to flow more efficiently through the exhaust system. This improvement in exhaust flow reduces backpressure and produces a deeper, more aggressive twin-turbo V8 exhaust tone while maintaining compatibility with the factory exhaust layout.
Constructed from Stainless Steel 304 using TIG welded joints and mandrel-bent tubing, the system ensures smooth exhaust flow, precise fitment, and long-term durability under high heat and load. Stainless Steel 304 provides excellent corrosion resistance and structural strength for reliable performance use.
