Does anyone have a pic (preferably) are can explain to me in detail what a 1995 GT Mustang's exhaust looks like stock? Or how can I find out if my exhaust has been upgradded. Thanks for the help!
Your headers will be crimped at the end right at the flange to restrict air flow. Aftermarket headers are compleatly round and are usually stamped w/ the companys name on it such as BBK.
The Stock H Pipe has 4 cats on it, aftermarket H Pipes have either 2 cats or non at all.
The cat back is pretty easy, it should sound stock or just look on the mufflers, the company name is usually stamped on them as well. Also aftermarket tail pipes ( which people usually get w/ an aftermarket system unless they just buy the mufflers) are 2 1/2 Inches.
Oh I see...thanks for the response. I figured my headers were still stock, but I was not sure about anything else. When I bought the car I found an invoice that said that flowmasters were put on there, but that is all it says, I think the price was like no more than $200.
