Alright, I have an 88 z24 and i just put a new stock muffler on it, I was thinking about extensions..but I don't know my pipe size? Should i just measure the diameter of the pipe or what? HELP!

that would be your best bet, but why didnt you go with an aftermarket muffler?

Well, what brand muffler did you get? Usually they're 2.25 inches.
