Off-road and competition use only. For off-road and competition use only. Not legal for sale or use on pollution-controlled motor vehicles. Not CARB certified.

About this part

A 3.5-inch heat-shielded catless downpipe set for the N63TU3, BMW's third technical update of the 4.4-litre twin-turbocharged V8. The turbochargers on this engine sit inside the vee, which means the downpipes run through the tightest and hottest part of the engine bay.

That is why the heat shielding on a part like this is doing real work rather than serving as a selling point: it keeps radiant heat off everything packed in around it. Going to 3.5 inches and removing the primary catalysts takes a substantial restriction out of the exhaust path on an engine that has plenty to give once it can breathe.

The N63TU3 spans several model years and body styles, so confirm your chassis with us before ordering rather than matching on engine code alone. A tune is required, these are for off-road and competition use only, and we do not ship them to California.

Fitment

We have not published a fitment list for this part yet. Rather than show you a table we are not certain of, we would rather you asked: send us your chassis code, engine code and build date through fitment help and we will confirm it against your car.

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.
