M8 F92 / F93

Catback exhausts and downpipes for the BMW M8 F92 and F93

On the M8 F92 you can change the sound with a Valvetronic or straight catback and add a catted or de-cat downpipe. These exhaust products are shared with the M5 F90, and for the M8 their names list the F92; the Valvetronic systems come in stainless steel or titanium. The magnetic carbon fiber paddle shifters for F and G Series BMWs are listed here too. BYC Performance imports these products from leading manufacturers around the world.

F92 Coupé, F93 Gran Coupé and F91 Convertible

For the M8, the product names list only the F92 Coupé. The F93 Gran Coupé has a longer wheelbase than the F92, and the F91 Convertible is not in the product names either. If you own one of these two, confirm fitment with your VIN on WhatsApp before ordering.

Valvetronic or straight catback?

A catback replaces the line after the downpipes, all the way to the tips. The stainless steel and titanium Valvetronic systems come with their own electronic control box and wireless remote; you adjust the sound by opening and closing the valves with the remote. The titanium version is the lighter one, and you pick a 76 or 90 mm pipe diameter and gold, blue, purple or original titanium color. The stainless steel straight catback does not have Valvetronic in its name, so if you want to change the sound with the remote, choose one of the Valvetronic versions. Tip options are stainless steel, gloss black and carbon fiber in gloss or matte finish.

Downpipe options

The 200-cell catted downpipe has a catalytic converter and the de-cat downpipe does not; both are heat-shielded. There is also a stainless steel downpipe whose name gives no heat shield or catalytic converter details; ask on WhatsApp whether it is catted or de-cat before ordering. Before buying a de-cat downpipe, check the emission rules where the car is driven, and send any software questions on WhatsApp.

Frequently asked questions

Do M5 F90 carbon body parts fit the M8?

The M5 F90 and the M8 have different bodies; hoods, diffusers, front lips and other parts in the M5 F90 category are for the M5 F90 only. The products that name both models are the exhausts and downpipes.

Can I fit just the catback first?

The catback replaces the line after the downpipes and can be fitted on its own; you can add a downpipe later.

When will my exhaust ship?

Lead time for sourced-to-order parts is confirmed on WhatsApp right after your order. Exhaust systems ship via partner couriers and carry a 24-month BYC warranty against manufacturing defects.
