Who told you a 94 cat was crap? Mine worked fine. Aftermarket engine builder/tuners like John Lingenfelter were able to build high HP emissions certified 383's, and claimed the cat cost less than 5 HP. Do you have any indication the stock/original cat is plugged? Do you have indication of high emissions?
In 96 they went to dual cats. They went to dual cats in CA in 1995 on the auto trans LT1's. Where are you located? CA is a problem with cat replacement. They enforce the Federal rule that the cat cannot be replaced unless it is certified defective, and it can only be replaced with a CARB approved cat. The HP is gained in replacing the intermediate pipe with a 3" mandrel-bent pipe, rather than the stock 2.75" crimp bent pipe. Replacing the muffler doesn't do much. A full catback provides the best gains. |

when i meant crap i read that they was restricted because they didn't want it to compete with the corvette ? & in 96 they put better cats on the z28s. i live in nc they said had put cats on so your says just doing a muffler & cats would be a waste of money? mines just stock i dont think its clogged or anything just was thinking outside the box & didn't wanna drop 1g on exhaust

Just changing the cat and muffler is not going to net you much of anything.
