DESCRIPTION
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.
Why Go Catless?
✅ Maximum flow — completely removes the bottleneck for peak power gains
✅ Faster turbo spool and sharper throttle response
✅ Loud, raw, and aggressive exhaust tone
✅ T304 stainless steel construction with heat-resistant OEM-style shielding
✅ Mandrel-bent piping for uninterrupted exhaust flow
✅ CNC-machined flanges and TIG welds for precise, leak-free fitment
✅ Bolt-on install — no cutting, no welding
✅ 1-Year Warranty — built to last
