need hi-flo cat

I'm trying to find a high flow cat for my 91 rs. The only one that I know of is Random Technologies' cat. I was just curious if there are any others and if anyone knows about the performance of these cats.
I'm thinking about just replacing the cat with a pipe if i don't find any cats that i like.

Catco and Car Sound also make good cats.

I just put a Dynomax Cat on my car. I liked the quality of it, but I don't think it flows as well as some of the others. I guess I'll find out when I fab up a piece of straight pipe this weekend.

The Random Technology one is by far the best, but you have to decide if its worth the money. I got a dynomax one and it didn't have the mounting flange on it so I just sent it back and got a chip with the money. But my friend has a Random Tech one on his 89 RS and it sounds great.

On camaroz28.com there is a GP for random tech cats. It is an excellent deal! We need more people to finish it though. Let everyone know. http://web.camaross.com/bb/Forum27/HTML/000257.html
