I have a pair of Dynatech PowerCat Catalytic Converters, I needed bullet cats for my long tube header install.

I've got a random tech cat behind my AS&M headers. Works fine, car passes emissions and makes the power numbers below.

My car has installed the Random Tech high flow dual cat Y pipe too, plus the SLP "2onthaleft" cat back....the sound of the cat back was improved to my ears and gained a few HPs....

I used a pair of Pypes high-flow minicats to please the emissions guys. I didn't notice a positive or negative difference before and after.
