I have found two different cats that are what I am looking for, but are seperated by $100. One is a Catco from Summit and the other is a Random Tech (I think) from TPiS. Which is better and why? Just so you know, the Catco is cheaper at a little more than $110, while the Random Tech is over $200.

Because people will pay $200...Buy the CATCO.

 

Well, in my case I've had my exhaust with and without the Catco converter. There was absolutely no sound or power difference with or without, and for under $100 - you can't beat that.

My car also "fast passed" the very strict Maryland emissions test with the converter. Most new Low Emissions Vehicles have trouble doing that!

I did a lot of info searching a few weeks back as I was replacing the cats in my car it came stock with dual cats. Random Tech would of cost me about $400 for two converters,but I ended up ordering two catco cats from Summit delivered to my door for around $130. They are 2.5 inlet and outlet which is a little bigger than my stock cats. Many guys on the board here use catcos I like them. If I really had a lot of work done to my motor I might of gotten the Random Techs but since your mods seem similar to mine I would get the catcos and with the money you save put it towards a new Torque Converter or something. If you are using only one converter get the Catco Hi Flows check out www.discountconverter.com they are a little bigger. I wanted to get them but I could not fit them under my car side to side.

Thanks guys. I am going to order a 3" In/3" Out Catco from Summit here in a few minutes. I didn't figure that it could be a bad cat, since Summit is a pretty well respected company and I wouldn't expect them to sell crap. Anyway, thanks for your help.

hahaha...I understand what you are saying, and I agree, but I was talking about quality parts specifically for our cars. You are very correct though about those things. lol

I just went through emissions yesterday and I surprisingly passed. When I got home I put in a replacement 3" straight pipe for my catco cat. I found that the insides of it were completely gone in only one year. Here in CT we have some pretty strict emissions but I still passed with basically no cat at all.
