what type of cats are you guys using? i'm thinking of the carsound units off ebay...only 60 bucks shipped. magnaflow makes them and their exhaust units are amazing. i was also thinking of the Stainles Steel Cat Converters unit off of JC Whitney. they are over 150 though. they are supposed to be one of the highest flowing on the market.

just curious, i'm in the market for one...single 3"

I was told that carsound 93500 series cats flow the best of all the carsound cats. I don't think it's a coincidence that it has the widest body and is made for the biggest CID engines.

Here's the best/only comparison I've ever seen. Perhaps there's something newer, but it's a start. http://www.ls1tech.com/forums/showthread.p...&highlight=cats
