Exhaust Advice for e63 650i
Discussion
Evening all, I did have a look around on the forums and Web but couldn't find what I was after.
I'll start by saying I'm something of a noob when it comes to mechanical alterations!
What I'm doing is removing my mufflers on my e63 650i and replacing them with straight pipe, what I need to know is whether the width of the straight pipe needs to be the same as the inlet for the tail pipe, then just welded together or whether one has to be larger than the other so that the fit into each other, then welded?
I have a welder who is prepared to do it for me once I get the parts, I know I need 2.25 straight pipe, just need to know what size inlet to get for the tail pipe, thanks in advance.
