NOT ROAD LEGAL
Evolve catless turbo downpipes for the S58 G80 | G81 M3 | G82 | G83 M4 in 304 Stainless steel. By eliminating the restrictive catalytic converters in the factory downpipes, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.
- Stainless Steel construction
- Tig Welded and back purged
- 3.5” diameter
- Fits to stock exhaust or any after market exhaust that fits the stock downpipes
- Allows faster turbo spool for better throttle response
