is it true that all the mufflers and back are all the same for all f-bodies, cuz ive got a firebird formula that is just sittin there with 3" pipes and i wanted to know if i can just transfer it over ? ? ? the firebird is a 92 the camaro 96. Will it fit?

That's a good question....93-02 would be the same for sure. As far as third-gens I don't know; I had a 89 iroc and the cat-back looked the same as the one on my 00...but I never measured them.

Yea cuz after the holidays im just gonna save my money for mods now. I spent like 700 bucks on gifts alone., and thats just for immediate family and close friends. But once this "christmas" thing is done. Im gonna build me a bigger monster. Wanted to out a 58mm TB on it so i have to do some porting. I also wanted to take the headers and port and polish those too. But who knows, for now its just muffler. For a deeper sound.

All of the cat-backs for 3rd gens and 4th gens are routed the same. Meaning from 1982-2002, after the trans, all of the catbacks follow the same path. Now where they differ is how the connect to that part of the exhaust. 3rd gens had a Y-pipe loop under the engine to the passenger's side through the hump on the passenger floor (reserved for a single cat) and meander back to the trans tunnel routing out the back. The LT1s had a similar route. The LS1 had the exhaust pipes come from both sides of the car to behind the trans into a Y-pipe meeting at the trans tunnel and routing out back. The sizes also varied, from 3rd gens 2-1/2" to LS1 with 3".
