Stock is 1.5" until the first muffler, then progressively smaller diameter from there. The tailpipe is like 1" OD.

Mine's 1.5" all the way through. I'll go 2" all the way through one of these days, not to "upgrade" the size or anything. Just because it matches my extractors, I have new 2" pipe sitting around and my exhaust needs rerouting.

It makes a bad sound.

2ā€ is massive overkill

I'd go 1.75" to the muffler with 1.5" tail pipe.
2" is unnecessary and just sounds like a fart ... ...
