Direct-fit cat delete test pipes for the E90, E92 and E93 M3 - no cutting, no welding, just slip-on and clamp. Designed for fast-road or track-day use with an ECU remap.
Unlocks up to 20 bhp and 20 lb/ft torque - dyno-proven gains when paired with a remap
Includes 2x OEM-spec gaskets for secure, leak-free fitment
Works with your stock X-pipe - a focused upgrade, not a full exhaust replacement
NOT road legal - intended for track, competition or off-road use only
Requires ECU remap to prevent CEL and realise full performance benefit.
