S55 Single Midpipe Upgrade for F80/F82 BMW

The RVNG 4" Stainless Steel Single Midpipe is the largest midpipe available for the S55-powered F80/F82/F83 M3 and M4 — one of the most cost-effective mods for your S55, worth 18+whp and 30+wtq with a tune. Replacing the restrictive OEM midpipe dramatically cuts back-pressure for faster spool, better flow, and a noticeably more aggressive note, while shaving about 17 lb versus stock.

Features

• Largest midpipe on the market — full 4" diameter for maximum flow
• Gains of 18+whp and 30+wtq with a tune
• CAD/CAM-designed flange for a seamless flange-to-pipe transition
• Handcrafted from mandrel-bent, TIG-welded 304-grade stainless steel
• Smooth radius bends to minimize turbulence and maximize exhaust velocity
• About 17 lb lighter than OEM
• Fits RHD and LHD with no modifications
• Compatible with OEM downpipes, aftermarket downpipes, and the MPE on Competition models
