I have a Civic with a D16 motor with Greddy kit pushing 6lbs of boost. I still have the stock cat on with a Greddy exhaust. My question is what kinda power would I gain from going to a high flow cat such as Random Technologies? Is it worth the $200 for a new cat? TIA

 

I think that would be your most bang-for-the-buck mod at this point.

Some of us just ditch the cat all together, but I didn't say that.

 

Definately Agree w/ the NO cat idea!!!
