A friend is looking to purchase a brand new quality high flow cat. Can anyone point me in the right direction?

Thanks--

 

IMO, N-Tech makes the best high-flow cat. supposedly, it flows 96% as well as a midpipe. also, the airpump hose plugs right into it just like stock with some modification, instead of having to fabricate some **** as with the Random Tech unit.

i have heard - by people that actually have them - that the Random Tech cat can not stand up to the heat of the rotary engine. also, the Bonez cat only gives a claimed 6 hp increase over stock. i think 96% of the flow of a midpipe (N-Tech) is a little more than 6 hp, so the N-Tech flows better.

 

Get your facts straight. I have the Bonez, no fabrication needed, the air supply tube is still there.

N-tech has a plugged hole "that can be used for the air pump with some modification." Straight from N-tech's website.

I have no experience with random tech, but I have read posts here - by people who actually have them - that they have fitment problems.

Ntech is cheaper than the Bonez though, good luck.
