Best Cat (under $150)
Im probably going to replace the at when I do my exhaust (if i can find some used headers already!). I was mainly thinking catco or carsound, but am open to suggestions. Which is the best?

A bunch of people use Catco. A TPI-type, single 3" slip-fit inlet, direct fit piece is under $120 from Summit. Wish I had gotten that one instead of the universal I ended up getting.

I just got a CarSound put on ... 59.95 + 10 shipping right to my door. The number is 1-877-722-3784 or www.testpipe.com
I am very impressed with the cat. The only thing is that it took a week for the cat to come. And the people on the other side of the phone were very hard to understand. Other than that ... i am VERY impressed.

I really wonder how the Random Technologies, supposedly the best, does against a 1 of those. There is a nice price difference between the 2.

CarSound make the best cat I think. They outperform the Random Technology. Check out www.car-sound.com for the dyno results. I got my cat for $59.95.

Sorry, I had the wrong website. Here is the correct site. Ignore the prices on this page. They are too high.

I think the 59 dollar cat is like the 6th or 7th one down.
Also check around http://www.mufflertech.com/ They have some deal going which offers 2 cats for 99 bananas. ($99 for you old school folk)

That is why I said to ignore these prices. This place charges too much. I got mine from mufflertech.com for 59.

I have the random tech cat
Yes its a little $$ but hey I wanted the best for my car. It made my flowmasters louder and I could tell a differance in power right away (I guess thats what you get when you have an 11yr old cat)
