catless to catted downpipe
Hi.
im currently running a catless downpipe on my 525D and want to swap it out with a catted downpipe. the car is stage one tuned and have the dpf and egr removed in the software. do i have to change the software in any way in order to install a catted downpipe instead?
i want to do the swap because its smelly and noisy
