I believe you said in another post that you don't have any exhaust right now. Correct?

Quit fretting and get the '86-up TPI for single 3" cat, a 3" high-flow cat and 3" cat-back. All it has to fit is your engine (it's a SBC, right?) and chassis (3rd gen, right?).

It will fit. All the smog fittings will be there. Just do it. If you notice my sig, that's exactly what I'm doing (except I went with the Hooker headers). There's no inspection station in the country that will fail you for having a CARB certified 3" system on an '83.

They were telling you that because it obviously wouldn't fit up with a stock 83 cat/cat-back. If you're redoing to the whole exhaust get everything in 3", which means ordering parts for a 86-92 single cat TPI car.
