Downpipes ? What's available and what benefit for 20 M8 Comp
I've been reading a bit about a downpipe upgrade but don't know a lot about the details
What section of the pipes are replaced? Post turbo, pre wastegate? Who makes the best ones? Tuning required? Warranty concerns? Thanks! |

The Downpipe’s for the f90 m5 fit the m8. There are two sections, primary and secondary. So total 4 cats in the system. Price usually comes down to fitment as they are truly metal pipes. Removal of the primary will trigger a CEL can be removed with a tune. Removing secondary will not. Dealer can flag car at any moment so warranty is always at risk. A relationship with your service advisor is important when modifying your car
I am running project gamma secondaries and it’s the right amount of additional volume. Maybe I pick up some HP. Never dyno the car. Smell is about the same as stock |
