BMW F80 M3, F82 M4 & F87 M2 Competition S55 Sports Cat Downpipes Ceramic Coated

The BMW F80 M3, F82 M4, and F87 M2 Competition S55 Ceramic Coated Sports Cat Downpipes are the road-legal upgrade for owners seeking more power, improved throttle response, and a refined exhaust note. Unlike decats that introduce excessive rasp, these Euro 5 200CEL sports catalysts free up the restriction of the OEM cats while keeping rasp to a minimum. The added ceramic coating helps reduce engine bay temperatures, lowering intake air temps and extending turbo life for enhanced reliability.

Crafted with a flow-optimised transition design, these downpipes improve exhaust gas flow for faster turbo spool, significant power gains, and a sharper driving experience. Manufactured to exacting standards with 100% TIG welds, OEM-spec 304 stainless steel flanges, and all original brackets and mounts, these downpipes are a true bolt-on solution that maintains OEM-style fitment.
