Theres not much talk about mufflers being used and how they go with drown. I have a RS4S with a standed dump,cat with a 3inch SS to 1 muffler from hi-tech mufflers (not a canon) and it sounds great but i just cant settle with the drowning. Im thinking of putting a hotdog in there and see what difference it makes.
+ if your warried about the heat shield on a different dump why dont you heat wrap it???
