WSTN BMW S58 M2/M3/M4 Catless Downpipes (G80/G81/G82/G83/G87)

Unleash Raw Performance from Your S58

WSTN Performance Catless Downpipes are engineered for the hardcore enthusiast who wants maximum flow, response, and sound from their S58-powered M car. Designed for the BMW M3, M4, and the latest G87 M2, these pipes eliminate the restrictive factory catalytic converters — unlocking faster spool, sharper throttle, and that brutal twin-turbo sound the factory setup chokes out.

Built from true stainless steel and wrapped in OEM-style thermal shielding, they handle extreme temps and abuse without flinching.
