Z28 Dual Cat Replacement - Help!
I have a 1992 Camaro Z28 with the 305 (LB9). It has the dual cat option. One of the cats have been leaking. I go and get it welded, and it eventually leaks again. Over and over. 
A few questions...
Do I have to run dual cats?
If I buy a set of headers (2055's), will I be able to use dual cats?
And finally, is there much difference in High Flow and Standard cats?

Re: Z28 Dual Cat Replacement - Help!
yes for emissions reason
Im not 100% positive on this but as far as I know, yes the hookers will fit
You wont notice an huge diffrence between standard cats and hi flows but they will make a diffrence and it would be recommended to go for hi flows.
Good luck
