Remus BMW G80 G82 Racing Secondary-Cat-replacement Tube (M3, M3 Competition, M4 & M4 Competition)

Turn up the soundtrack of your G80 and G82 with the Remus secondary decat centre pipe

Free the S58 with a centre section upgrade that unleashes a hard edged motorsport tone and sharper throttle response. This Remus secondary catalyst delete midpipe replaces the factory secondary converters on the G80 chassis M3 and G82 chassis M4, including Competition models, and delivers a deeper, louder, more race inspired note while improving gas flow for reduced restriction.

Built from premium stainless steel with a shot blasted finish, this precision made replacement section upsizes the factory 70 mm pipework to 76 mm for stronger flow and a more visceral soundtrack. Handcrafted in Austria and designed for an exact fit, it is a proven, high quality track solution that looks as good as it performs.
