BMW M4 G82 Performance Exhaust Upgrade – Valved Quad Exit with Black Chrome and Carbon Fibre Tips
Transform your BMW M4 G82 with a premium cat-back from Remus. This valved system delivers a fierce motorsport character when you want it and a refined tone when you don't, while keeping full control through the factory electronics. With quad 98 mm outlets in deep black chrome with real carbon fibre inserts, it looks as serious as it sounds.
Engineered for the 3.0 S58B30A 375 kW platform from 2021 onwards, this upgrade is all about sound, flow and quality. We fit these regularly at MJ Modifications and our customers love the finish, the valve functionality and the way it sharpens the driving experience.
- Factory valve integration – uses the original actuator and drive modes, no extra remotes required
- Quad 98 mm straight-cut tailpipes in black chrome with carbon fibre inserts for a bold, motorsport look
- Bead-blasted, full stainless steel construction for durability and a premium finish
- Freer flowing design for reduced backpressure and a clear performance uplift
- Lightweight construction compared with the stock system
- Precision fit for the G82 chassis – designed for a hassle-free install
- Crafted in Austria with meticulous attention to detail
