I leased my C63 a month ago. I just got my stage 2 ECU tuned and want to add downpipes to it.
I am concerned if removing the stock pipes and adding aftermarket downpipes would harm my lease when i turn in the car??
Anyone got experience with this situation

the only way to remove original pipes is to cut them out or drop tranny and then remove them

It a lease car. Don’t waste any more of your money. Not much more to gain from down pipes. You will have to pay again to return back to stock when your lease is up. Not worth it.

Doesn’t the tune void the warranty?

The stock downpipes are pretty restrictive. Adding downpipes would product significant gains on stage 2

We have had tons of leased cars do downpipes + tune. No issues returning as long as the car is brought back to stock

Remove the OEM down pipes without cutting.
I have a set of catless down pipes in stock ready to ship.

if the tune causes problems somehow and the dealer can prove it then yes. But I know people who got warranty work done while tuned and had no problems. But there are others who have been denied due to modifications.
