Hi all!
I have a Mercedes Benz C300 coupe 2018 and I'm in 2 minds about a stage 1 remap with pops and bangs.
Does the downpipe need changing in order for the pops and bangs to be fully effective? I've spoken to a couple of companies, some say I need to change the downpipe and some day I can keep the stock downpipe. Anyone have any experience or recommendations?

I'd rather not change a lot with the exhaust (i.e. cat deletes, res deletes) as I don't want the side effects! Any advise would be great
Thanks all

i belive you need to have Cat-Less downpipe for burble tune otherwise you cat will get clogged
