I agree with everything stated here.. some great advice- seeing as I was looking for the same awhile ago and this is what I came up with too..

Thought I'd add that mandrel bending is where the pipe is bent uniformally the meaning that if you have a2.5" pipe and you bend it it would still be a smooth 2.5 inches at the bend. This allows for the most consistant air flow.

Average muffler shops though, just use crunch type bends where the bend size is just kind of crunched or krinkled at the bend..

Also a question on headers I have 4-1 VS. 4-2-1 what's the difference-- and what's preferred=-- and why??
