Our N54 catless downpipes are made from T304 stainless steel and are 2.5" in diameter. They remove the primary cats allowing the turbo's to spool up faster providing greater throttle response whilst lowering EGTs (Exhaust Gas Temperatures). In the UK cars will still pass MOT with these fitted and secondary cats still in place. 

They fit both RHD and LHD and have 100% fitment.
