i have 2 questions, one-which cat will fit our cars and two would it even be worth it or is ours already basically high flow

 

hard to say right now..haven't heard of any companies that are making high flow cats for the 06

also the oem is a specific 3 way cat or something like that which helps with the emissions

 

I have been looking into this as well. I thought I saw one from Mangaflow universal fit, but I didn't save the location. Someone I know recommended the high flow cat to me versus replacing the whole exhaust system.

If the FG2 has one, I would not think it needs to be changed. However, I do not believe the Si has a high cat. Anyone know for sure?

 

well true but i live in a place with no emission test so im not to worried about it

No it doesn't.... When I looked in mine during the install of my EVO2 it was like a beehive comb in there.

 

any suggestions on what company i should call to see if one is in production? CATCO?
