Catco for your model & engine, a direct fit. About $120 at Summit.

thanks shifty...will the flange bolt right on to the hooker 2055 headers?...or mosy 3 inch y-pipes...I'm guessing it will, but what about for my 2 1/2 inch I-pipe...does summit sell the reducer for a 3 inch cat to a 2 1/2 inch I-pipe?

Which series is it? I haven't a clue what all the functions mean under the universal cats.

The universal fit cats are like 12" long, the stock cat in my TPI was maybe 20" long. Universals will take some fabbing to get them installed I believe. I have magnaflow cats on my car and they get the job done.

I'm planning on going 3" in/out with a magnaflow 1-in 2-out muffler and the piping custom mandrel bent. So length doesn't matter, I just want to know why there are so many different universal cats and which one I should get.

Catco is ok, but for the best flow, I think Random Technologies still rules the roost.

try thunder racing, the random tech cats are a bit pricey compared to some others, but many places say they are THE best flowing cats you can get. and of course ... you usually get what you pay for... i bought a magnaflow cat to go into my random tech cat-back and i'm gonna have to fab all kinds of s**t to get it to fit ... i really wanted the random cat to begin with but i passed them up because of price and money issues .... which i now regret. here's a link to thunder racing and the random tech cats :

good luck!
