Muffler delete
I have a 2018 e63s and I’m looking to remove the mufflers to make the car louder.
I currently have the renntech EVM and a ECU tune. I’ve been reading that if I just remove the mufflers without coding something for the flaps I will throw a CEL. However if I have the EVM is there a way to incorporate the EVM some how to make the car think the flaps are still in but in reality there won’t be at the mufflers and it will just be straight pipes from the H pipe all the way back?
