  • Best type of cat?

    My catalytic converter is stock, and it is making some wicked a$$ noises. I have been wanting to get a new one and have decided to get one. What is the best type of high flow cat on the market? I need suggestions. Thanks in advance.

    Car Sound cats are pretty good from what I've heard. I don't have any cats on my car.. :D People have also recommended Catco high flow cats, and Magnaflow high flow cats. Take your pic. The Car Sound cats are your best bang for the buck I believe.

            i think that i have read that some people with the carsounds cats thought the catco were not as well made. but i don't think i have heard anyone with a catco say anything bad about it. try searching for both and see what people have to say.

              I believe random tech is the best(flows the best at least), however very expensive.

                Well, I had some crappy performance on the highway when I went to take the SAT saturday, so I just gave in and got a high-flow Catco catalytic converter. We took it off and set it down and when we picked it up there was a huge pile of dirt, grim, and grit. We looked in it and it was broken into 3 pieces.

                The new Catco converter is SOOOOO much of an inprovement plus it made my exhaust a little louder on the highway and a lot louder (in a good way) idleing and driving around town. It sounds SOOOOO much better. I love it.

                Thanks for all the suggestions.

                  Carsound has treated me pretty well. I also like my Walker as well.
