What high flow cat are you guys using?
Ive got a 2000 si w/ greddy exhaust on it and was wondering what people suggested for a high flow cat. Or are they all pretty much the same?

I heard magnaflow/carsound was the best aftermarket or high flow cat out there, unless your turbo or putting down some serious N/A numbers you dont need a high flow cat or straight pipe, leave it alone

I just took mine to a local muffler shop and had them delete the cat. I think I gained some power from it, but its illegal. BTW they only charged $20

I ran the carsound cat on my last car without any issues. Put 385whp down through it. Plus for $50 bucks you cant complain.
