What has anybody heard about high flow cats and which ones actually do better then the stock ones? Im thinking about ordering MAC headers and they come with highflow cats but is there any flow numbers out there that really tell what HighFlow Cat is better.

Thanks

I don't have a link to the site, but Random Tech and Carsound get a lot of good comments.
