High flow cats
Are high flow cats that important? I am looking to buy some headers. I have a magnaflow x-pipe, and Corsa cat back exhuast. I dont race, but I may take it to the track 1-2 times a year with a club if I can.

Hi-flow cats
I don't know your definition of important, but when I put the headers and full 3" exhaust system of my vert I put RT's 3" hi-flos on it. I don't have dyno tests to show any gains although I am certain they are much less restrictive than the stock 2 1/2" set up.
