Evolution Racewerks Sports Series High Flow Catted Downpipes - S58 (M2/M3/M4)

OVERVIEW

Want the power gains of a downpipe upgrade without giving up your catalytic converters? The Evolution Racewerks Sports Series High Flow Catted Downpipes use a high-flow 200-cell metallic catalytic converter core in place of the factory ceramic units, delivering meaningfully more flow while still passing emissions. The factory donut flange design and slip-on connection are retained, so these bolt in with no compatibility issues on factory or aftermarket exhaust.

SPECS

• High-flow 200-cell metallic catalytic converter core (vs. factory ceramic) — more flow, higher heat tolerance, lighter weight
• Replaces the primary catalytic converter sections (2 primary + 2 secondary cats on G8x/G87)

• CNC-machined billet 304 stainless steel 3.5" V-band flange, duplicated from the factory turbo housing
• Retains factory slip-on connection and donut flange design — 100% bolt-on
