It comes with a Y-pipe and a high-flow cat and install kits for 350. Think this is a pretty good deal for the HP gains? It will be my first performance mod to my max. Any suggestions for something else or go for it. And I will be putting in a CAI soon also.

 

Forget the cat. That money is better spent on other things.

 

like........????????????

 

Anything.

The OEM cat has 2.5" inlet and outlet. It matches up perfectly with a Y and catback. Unless yours is broken or melted, just leave it.

 

I can attest to that, I have that setup and the Cat does nothing really.. Time to fish in the garage for the stocker

 

the high flow cat wont do anything for you unless you are boosted... i like the idea of the custom enterprise y-pipe tho...

 

okie dokie
how about a y pipe and a CAI?

 

Sounds like a good plan.

 

y-pipe - definitely
cai - maybe
