BMW F80 M3, F82 M4 & F87 M2 Competition Spool S55 Race Downpipes

The Spool S55 race downpipes for the BMW F80 M3, F82/F83 M4 and F87 M2 Competition are mandrel-bent, TIG-welded 3-inch 304 stainless steel built for maximum exhaust flow.

Why you need it

Downpipes are one of the most cost-effective upgrades for a turbo BMW. Lower backpressure helps the turbos build boost with less strain, and Spool rates these at 20 to 25 hp and 25 to 30 lb-ft at the wheels. Add a tune for bigger gains and a more aggressive note.
