Remus BMW G80 G82 Racing Secondary Cat-Back Exhaust System for M3, M3 Competition, M4 and M4 Competition
Upgrade the sound and performance of your BMW M3 G80 or BMW M4 G82 with the Remus Racing Secondary Cat-Back Exhaust System. This valved Remus cat back exhaust is designed for the G80 M3, G80 M3 Competition, G82 M4 and G82 M4 Competition, with and without GPF. Expect an aggressive racing sound, reduced back pressure, lightweight construction and perfect fitment. Handmade in Austria from high grade stainless steel, this Remus G80 G82 cat-back exhaust is built for enthusiasts who want the ultimate track-focused BMW M exhaust.
We have fitted this Remus G80 M3 and G82 M4 cat back system on customer cars here at Nforcd and the feedback has been outstanding. Deeper tone at idle, pronounced bark under load, excellent valve control via the factory actuators and noticeably freer revving thanks to lower back pressure. If you want a BMW M3 exhaust or BMW M4 exhaust that transforms character while keeping OE valve functionality, this is the one.
