BMW F91, F92 & F93 M8 Spool S63 Stainless Steel Race Downpipes

The Spool race downpipes for the BMW F91, F92 and F93 M8 replace the restrictive factory downpipes on the S63 with smooth-flowing 304 stainless steel.

Why you need it

Downpipes are one of the most cost-effective upgrades on a turbocharged BMW. Lower backpressure lets the turbos build boost more easily and puts less strain on them. Paired with a tune, they unlock real power gains along with a more aggressive exhaust note.
