BMW G80 M3 exhaust systems

Get more sound and performance from your BMW G80 M3's S58 engine with an exhaust upgrade. This page covers exhausts for the 2021+ G80 M3: valved rear sections, mid-pipes, downpipes, exhaust tips and valve controllers.

Brands include Deep Tone Industries, Scorpion, Valvetronic Designs, Akrapovič, Milltek Sport, Remus, SLN Performance, Active Autowerke and our own R44 Exhausts, plus Genuine BMW M Performance exhaust parts.

Not sure where to start? A valved rear section keeps the car civilised when you want it to be, while mid-pipes and downpipes change the sound and, with a tune, the performance. Chat to our team for advice, or book UK fitting at R44 HQ in Wembley.

G80 M3 Exhaust Systems FAQs

What's the difference between a rear exhaust, mid-pipe and downpipe?

A rear (often valved) exhaust section mainly changes the sound and look. Mid-pipes replace the centre section and are a popular way to add volume. Downpipes replace the section directly after the turbos and are usually paired with an ECU tune.

Do I need a tune after fitting downpipes?

In most cases, yes. Downpipes change the exhaust flow the engine sees, so they're normally fitted together with a suitable ECU tune. Check the product description, or ask our team.

Do G82 M4 exhausts fit the G80 M3?

In most cases, yes. The G80 M3 and G82/G83 M4 share the S58 engine and exhaust layout, so exhaust systems are usually shared – but always check the fitment listed on each product.

Are aftermarket exhausts road legal in the UK?

Some exhaust parts are sold for motorsport or off-road use only, and louder systems can affect your MOT and insurance. Each product page explains its intended use – if you're unsure, ask our team before buying.
