Need some performance rotaries to chime in:

(please comment from experiences, no guessing please)


Looking for best high-flow cat for my 1st gen. Important goals for cat:

1) highest flow cat ( most hp next to a straight pipe)
2) longevity/ durability (hot rotary breath)
3) still pass CA smog for many years
( not fail after less than a year as I have heard some burn out)


* heard some good things abut the bonz cat and random technology cat, who has heard better thngs about either?

* feel free to suggest any other models you know of that have been "proven." and where to get a good price


thanx in advance,
rotarypwrd tomas

 

As far as longevity, as well as simplicity, I am told that the cats that use a stainless steel element are the best. They can withstand a lot of heat, and on top of that, an air pump is not required to keep it from overheating. So basically you can keep a converter and ditch your air pump (if you have one, and dont need it for port actuation, i.e. turbo cars)

 

thanks mrdirt, good advice.

anyone else? experiences with any so-called high-flow cats on rotaries?

 

I've heard the Bonez high flow cat is the best for the rotaries.

 

Bonez!

Who sells 4" cats? I dont want to have to buy two reducers for something that will rarely see time on my car.

 

http://www.randomtechnology.com/ They will hold up to a rotarys heat.

 

The core is 4" inlet and outlet come in 2", 2.5" and 3"

 

Sorry about that, I meant 4" in/out.
