I already put up a post regarding the best cat, but no one seemed to wanna answer me. Just need help deciding to go with a catco, dnyomax, or magnaflow cat. I can get the magnaflow the cheapest (I think $109 at summit) and the catco and dynomax are both around $120 for my '89 Camaro IROC-Z. Just let me know which one flows best/ gives most power and best durability. Thanks. -89IRO

 

Go with the Catco, I've heard good things.

 

Catco.

 

I've heard good things about Catco too.

 

I have had a big problem with my 3" universal Catco cat. This is the one that is 50 bucks, I don't know if they make a better one or not. It has started coming apart and blowing into the muffler, and it makes the most incredibly loud and annoying raddling noise because of it. Should of known better than buying a 50 dollar cat. I'm just gonna gut it out, and run a 3" piece of pipe through it, so it looks like I have a cat, but it will really just be a straight pipe. Just my .02

 

Direct fit Catco for your model of car and not the one size fits all.
