The key is to get some that are Metal substrate and not ceramic- The ceramic cats just don't hold up well on high HP applications--Most manufacturers make them--Magniflow,Walker, Catco, Random Technology, Performance Curve---prices vary by quality warranty etc.
range from $300 to $60------I bought the Performance Curve metal substrate , Stainless spun 3" bullet type cats directly from them for about $60 each--So far no problems--passed calif smog although they say " not approved in calif "
Don't know why--I think they wouldn't pay the EPA the big bucks to get them officially approved--???

I purchased Kooks LT headers and HF cats from corvette garage, but after adding the P1SC i pulled the HF cats off. Maybe 1,000 miles on them. If your interested I am willing to sell them.

After an hour of driving I got a CEL before I had it tuned. it was a COT, out of temperture range, High Flows run hotter then the sensor likes. I believe the tuner merely adjusted the COT tables...
