Remus Valved Cat-Back Exhaust System for BMW M8 Competition F92 (2019+) | Non-Resonated Stainless Steel | Quad 102mm Carbon Fibre Tips | OEM Active Valve Control | Performance Sports Catback Upgrade 8 Series S63

Valved performance catback for BMW M8 F92 Competition 2019 onwards

Unlock a fierce, motorsport-inspired soundtrack and serious flow with this Austrian-built REMUS performance exhaust upgrade. Engineered to retain factory valve control, this dual exit system delivers a deeper tone at idle, a refined rumble on the cruise, and a thrilling roar under load. The result is a premium, high-flow catback that looks as good as it sounds thanks to four carbon fibre outlets with titanium inners, all finished to an exceptional standard.

We have installed this system on customer cars and the feedback has been superb. Crisp valve operation, precise fitment, stunning tips, and a noticeable reduction in back pressure for sharper response. If you want a quality stainless steel sports exhaust that elevates your M8 without compromise, this is the one.

• Direct-fit valved performance exhaust that keeps OEM valve electronics
