BMW F80 M3 / F82 M4 S55 Rvng 4" Single Midpipe

The Rvng 4" dual-to-single midpipe replaces the restrictive OEM midpipe on the S55 F80 M3 and F82 / F83 M4.

Why you need it

Swapping the factory midpipe cuts back pressure for faster spool, better flow and a much more aggressive note. Rvng quotes 18+ whp and 30+ wtq when tuned, and a 17 lb weight saving over OEM.
