I pipe exhaust question???

I've been shopping around and would like to know where it would be possible to get the best deal on a new or almost new I pipe for a 1995 Z28? Thanks for any help!

junkyard or an exhaust shop. I know with my friend, we asked a local muffler shop to hang onto any I-pipes off any V8s that upgraded their exhausts. They usually throw them away anyways so the $20 offer was accepted.

I have a 1994 3.4

What year of Z28 should I get an I-pipe off of to fit my car?

Thanks

any year without dual cats
