what is the size of oem exhaust pipe?
just under 1.75 i beleive...
1.75 OD. I would know, I took my muffler off and got pipe bent.
Yea it's 1.75"
The biggest you could go before you start having problems is 2", so if you get custom piping, try not to get much bigger than that. And DON NOT let anyone convince you otherwise.
ya unless u go with forced induction u will see some losses after 2" but some people think otherwise...
Umm I'd like to see numbers backing that up. You guys are probably right, but without any dyno sheets, who knows.
All I know is the stock system has a lot of bends that would benefit a larger diameter size. By the looks of it, the pipe from the cat to the stainless flex is 2 inches and from then on, it's 1.75... That would mean that the cat is a 2 inch, and that all the bends from the start of the exhaust system are restrictive. From then on 1.75 was "good" enough.
The problem I see with the 1.75 inch pipe are the two 90 degree bends near the rear axle. 90 degree bends are restrictive on any pipe size, therefore going bigger usually helps.
To make a better assesment, I should be buying a pressure gauge this summer and will test the stock system before and after the cat, with and without the muffler.
def. update us when u do thisQuote:

It's an online magazine. Best thing about it it's free.
You will lose some of your torque if you got w/ a 2" all the way back but gain a little hp.
Any bigger than that and there wont be enough back pressure.
aaahhh another "which size exhaust pipe is better debate?"
this has been argued so many times.......ugh :roll:
