BMW G80 M3, G82 M4 & G87 M2 Spool S58 Race Downpipe

The Spool S58 race downpipe for the BMW G80 M3, G82/G83 M4 and G87 M2 cuts exhaust backpressure so the S58 can make more power with a tune.

Why you need it

The factory downpipe is a major restriction once you start adding boost. This 304 stainless downpipe reduces backpressure and, with proper tuning, Spool rates it for gains of over 100 hp. It is built to handle the heat and stress of hard driving.
