We are proud to introduce our new R44 S58 Catless Downpipe for 2021 G80/G82 M3 & M4. Reduce backpressure by eliminating the restrictive catalytic converter in the factory downpipe which results in a faster spool, an increase in power and a more aggressive exhaust note. Handcrafted from stainless steel and CNC precision-machined flanges constructed from billet 304-grade stainless steel.
- Made from hand-crafted, tig welded 304-grade stainless steel.
- Smooth radius bends to decrease turbulence and increase flow.
