RVNG Stainless Steel Dual to Single 4” Midpipe
We are proud to introduce our RVNG 4″ Stainless Steel Single Midpipe for the S55-powered F80/F82/F83 M3 & M4 — the largest midpipe available on the market for these models. This upgrade is one of the most cost-effective modifications you can make to your S55, with potential gains of 18+ whp and 30+ wtq when tuned.
By replacing the highly restrictive OEM midpipe, back pressure is dramatically reduced, resulting in faster turbo spool, improved exhaust flow, and a noticeably more aggressive exhaust note.
Designed to fit perfectly on both the F80 M3 and F82/F83 M4, our midpipe delivers an instant performance difference the moment it’s installed. You’ll also benefit from a 17 lb weight reduction compared to the OEM setup.
Constructed from mandrel-bent, TIG-welded 304-grade stainless steel, this system is built for maximum durability and performance. It’s fully compatible with OEM downpipes, all aftermarket downpipes, and the M Performance Exhaust (MPE) found on Competition models.
Features:
- Largest midpipe on the market — full 4” diameter for maximum flow
- Gains of 18+ whp and 30+ wtq when tuned
- CAD/CAM designed flange for 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
- Faster turbo spool and deeper, more aggressive exhaust tone
- Fits both right-hand drive (RHD) and left-hand drive (LHD) models with no modifications
- Fully compatible with OEM mufflers and MPE Competition exhausts
- RVNG Lifetime Warranty against defects and fitment issues
Compatibility:
- 2015–2019 BMW F80 M3
