I am getting ready to buy my headers and exhaust and i was going to replace the catalytic converter with a high flow one. What are some of the choices and has anyone done this and noticed improvements in sound and power.

The only one i know of is Random Technology

Any info would be great

Thanks

 

You might want to check out Carsound,i presently have one on my Tib but getting another one cause im changing my exhaust system.Im going with a 2.5 or 3 inch inlet.Not sure Yet!!
Go with Carsound!!!!!!!!

 

Random Tech and Car Sound are the 2 "known" names in GOOD cats.

Catco brand cats are cheaper, but not known to be as good.

 

Random!!
Is there a homepage from Carsound Cats avaliable?
I want to see if there are any dyno runs with the Carsound installed?
I was on the Random Technology site and the Dyno numbers are pretty impressive?
I wanted to compare the two ad see the difference. Thanks!!!!!1

 

there was a big thread on the rx7forums discussing the so called high flow cats, and the thing is there are only 2 differant types of cats that are allowed to be used and the only differance between so called high flow cats and regular ones is that the openings are bigger, annd they are usually one piece, and shiny, other than that they have the same flow because the cat is functionally the same

 

Then those guys at the Rx7 Board don't know their ass from a cat converter.

A "High flow" cat converter has fewer internal plates, and a different internal design than a standard cat. It is designed with more internal surface area, for the same ammount of "cleaning" yet offering less backpressure due to the fewer plates.

All 3" opening cats are NOT the same. Random Technology cats are expensive for a reason. Catco cats are cheap for a reason. There IS a difference.

 

Random!!
I called up a shop to check price on a Random Technology Universal Cat and they quoted me $225US including shipping for the 2.5inch inlet IN and OUT.This is a little pricey but was wondering where i can determine pricing for a Carsound Cat!!
Is there a webpage for it!!
Or do you think i should just go with carsound bebause there wont be much of a difference in performance.What do you think?

 

I have seen OBX high flow cats on ebay for 50-70 does any one know if these are any good I was thinking of getting one.

 

wow,... thats a good price

Can anyone shed light on this?

 

I rate OBX up there with APC in product quality. I would NOT reccomend them.
