FTW I have no experience with these or this site
However, if a stock y-pipe will work and you cannot find one (I'll actually be removing my stock 93 y-pipe next weekend), this is probably the cheapest option

Elderbrock has 2 bolt flange , the factory manifold has three.
I bought a new magnaflow, y pipe and cat , to pass inspection.
I could only use the cat, y pipe wouldnt fit.
Look into a decent muffler shop, is my best advise.
