About this part

Catless heat-shielded downpipes for the S68 in the G90 M5 sedan and G99 M5 Touring. The S68 is the twin-turbo V8 that replaced the S63, and in this car it works as part of a plug-in hybrid driveline with an electric motor in the transmission and a 48-volt system alongside it.

Removing the primary catalysts on a V8 this size makes a large difference to exhaust flow. The heat shielding matters more here than it would on an inline-six: the turbochargers sit in the vee, underhood packaging is tight, everything runs hot, and the hybrid driveline adds components that do not tolerate heat soak well.

A tune is required. These are sold for off-road and competition use only and we do not ship them to California. If your G90 has to pass an emissions inspection, this is not the part for it.

Common questions

How do I know this part fits my car?

Check the fitment table on the product page: it lists the chassis codes, engine codes and model years the part is sold for. If your car is not on it, or the page says the list is still being confirmed, message us with your chassis code, engine code and build date before ordering. A VIN makes it quicker still.

Do I need a tune?

Every product page answers this directly. As a rule, downpipes need a tune and intakes, charge pipes and cooler guards do not. A downpipe on the factory calibration leaves the engine expecting a catalyst that is no longer there, which sets a check engine light and can put the car into reduced power.

What does "off-road and competition use only" mean?

It means the part removes or alters emissions equipment. It is not legal for sale or use on pollution-controlled motor vehicles and it is not CARB certified. Fitting one to a car driven on public roads is the owner's decision and the owner's responsibility. We do not ship these parts to California.

Can I pick up locally instead of paying for shipping?

Yes. Choose local pickup at checkout and no shipping is charged. We are in South Florida and serve Miami-Dade, Broward and Palm Beach. Wait for the ready email before making the trip. Picking up also means we can confirm fitment with you at the counter.

How long does shipping take?

Orders ship from South Florida to all 50 states. Handling and transit times are on the shipping page. Oversized parts move as freight rather than parcel and cannot be delivered to a PO box; where that applies the product page says so and the surcharge appears in the cart before you pay.
