I'm trying to keep my car legal. Is there a big difference in running a high flow cat compaired to the stock cat? Motor is a b18c1 port and polish head, skunk 2 valve train, type r pistons, and block was honed. I know i'm not going to be getting an extra 50hp but is it worth all the money. I am getting a type-r header and a cat back exhaust, megan probably. Or could i make the type r cat work, is it the same as a gsr? any info would help.

 

the stock cat will be restrictive with an all motor setup or any setup at that. get the high flow

lol ...what are you talking about?

To the OP:
If your setup was a salsa...it would probably be a medium/mild. lol (im not making fun of you, its a nice set up). At this point, you probably wont see too much of a gain from a high flow cat. You might see a couple of horsepower if that. However, sometimes high flow cats cause the CEL to come on on OBD2 cars.

The stock cat is not very restrictive. However, it does have a small diameter. The JDM ITR uses a 2.5'' cat. You could use that but you'd have to buy a clockable flange and reclock your exhaust. The S2000 uses a high flow cat from the factory. I dont know if this would fit onto an integra without modification, though.

Glad you're leaving your cat on.
