I'm starting to finalize and order everything I need for my new exhaust. So far I've ordered

Hooker 2055 headers from Jet Hot

Banks 3" Stinger Cat-Back


Now I just need to find a proper high flow cat that will fit. I've been looking on summitracing.com. I'm pretty sure I'm going to get a Catco cat, but I don't know exactly which one is right for my application.

I know I need one with a 3" inlet/outlet and an AIR tube (I live in CA), but there are a bunch listed with this specs. Some are 14" in length and some are 16.5" or 18". Also, some are made for 7.7L engines or smaller and some are 5.9L or smaller.


I have a 92 Camaro RS with an L03 engine in it. What size/lengh cat do I need to get in order to have it fit right? The one's I've listed are all universal fit. Is there disadvantage to this? And would a 3" in/out Catco cat be good for my application?

Thanks in advance guys


EDIT: I also found a direct fit catco cat with the 3" inlet/outlets. It's part number 9118 on summit.

Come on guys!

Anyone have ANY insight?
