Summit,
Magnaflow spun cats. I think they flow the best out of all I have seen. I am going to run the 3 inch on mine and have the e cut out for race time.

Random Technology I have heard flow more, but they are pricey.
Gone, but not forgotten!
Magnaflow eh. I had those cats recommended to me once. They aren't too pricey either, are they?

I swear vehicles had 80k mile warranty on the emission bits.
What makes you believe your converters are not functional anymore? They don't just GO BAD

Let's face it, the red hair... makes 'em wet.
Make sure you don't throw those old converters away, they are worth some money. I'm fixing to sell two used cats off a 98 LS1 for $145. Jusy FYI

LS1tech.com There are several guys buying converters for the platinum in them. I think the ls1 converters are a little higher, but all GM LSx converters are worth more than most I think. Just do a search and ask them what they will give you for what you got?

Thanx for the help. An my warranty was voided by my dealer since thay have put an engine, rear end, 2 trannys, and 3 flexplates in my truck. I found this out after i baught it and killed a flexplate. The preavious owner was a nipple head.
