MUST-HAVES
Exhaust system suitable for BMW M3 F80 - GRAIL valved system with ECE approval
For the M3 saloon F80 with the S55 biturbo you will find the GRAIL valved system suitable for BMW M3 F80 here - in 3 or 3.5 inch, hand-built from stainless steel and with ECE type approval. The F80 gains a distinctly more present voice than standard while staying easy to live with when the valves are closed.
Driving legally without a registration entry
ECE type approval makes an inspection appointment for the system unnecessary - fit it and drive. The valves run on your M3's factory control, operated by drive modes and the M buttons. More systems for BMW M models are in the GRAIL brand collection.
Installation in our workshop in Essen
Ordering with fitting means a 50% deposit and the rest after installation. The appointment usually takes only a few hours - which is why F80 drivers come to Essen from all over the country, not just from the region.
Frequently asked questions about the M3 F80 exhaust
Does the GRAIL system on the M3 F80 need a registration entry?
No - it has ECE type approval, so no entry is needed as long as the engine and exhaust of your F80 are otherwise standard.
3 or 3.5 inch on the F80 - what is the difference?
Both deliver the full S55 voice; the 3.5 inch version sounds a shade fuller. We are happy to advise before you order.
Does the F80 system also fit the M4 F82?
There are separate versions for that - you will find them in the exhaust systems suitable for BMW M4 F82 / F83 collection.
How quickly can I get a fitting appointment?
Once the deposit is in we agree the date with you directly - as soon as the system is with us in Essen, we fit it.
