Default Looking for Universal High Flow Cat part # and specs, or suggest a 3 inch High Flow

One time I found a page that listed the Catco brand units. It listed shape, inlet sizes, extior dimensions and part numbers.

Im looking to spec a high flow 3 inch cat, if anyone has suggestions feel free to post them as well.

Trying to get the best value for the money, not interested in pre made mid pipes unless they are very low cost.

Contact Road Race Engineering for one, that's where I got mine ($100) It works really well, it's the only Cat I have and I've never gotten an CEL.

I bought my high-flow cat from Performance Curves for $65. It's a Magnaflow (same as Carsounds) 3" in 3" out works great!

I've tested 3" catco cat against catless pipe in 3" diameter on a ~300 hp engine in my other and saw no difference in 1/4 mile speed, et. The only thing I noticed is slightly lower exhaust tone and 50 rpm decrease in spoolup.

Not junk in my book, especially given that fact that when I got the car tested for emissions, it put out number much lower the newer cars from the factory.
