Catalytic converter ???'s Well I had been having a nasty rattle from the underside of my '98 z28 for a couple months and have finally traced it to the passenger side catlytic converter (its broken up inside and rattling around). I took it to the local shop and they quoted me $350 for a new cat.
I have seen aftermarket high-flow cats for half that much. Now what I want to know is (1) will i pass CA emissions w/ high-flow cats, (2) will the aftermarket cats break down on me like my factory ones did?
Also, would going to an aftermarket catted y-pipe make a noticible power difference? And would i pass smog with that?
Thanks.

You cannot move the cats from the stock locations and pass in California. Your best bet is to pick up a set of used ones off the boards and bolt them up. You'll need to find out which years you can use (I think 98-99) and buy some from someone who has a set laying around. You could get some shorty headers and a catted y-pipe to match that keeps the cats in the same location.
This is a really nice setup done by a Oxidizer (works for Magnaflow) to another board members car. Notice the Overhaulin on the floor?

I actually have shortys i plan on installing, so the y-pipe would be catted as described. But yeah, I think I'm just going to try and find some take-offs from a local slavage yard or something.
if you want to purchase some hi-flow cats just make sure you put them in the stock locations.... it really doesn't matter if they're OBDII compliant just as long as it passes the sniffer

your local dealer should be able to replace it for free under those cirumstances
