I have a 2000 GP top swap with a Gen3, xp cam, mild ported heads, 42lb injectors, HAI, headers. I switched from a 3.4 to 3.2 a while back and was always curious about how much of a power difference that makes. What do you guys think? How much HP? I'm sure its a decent gain considering I can feel a difference.
Also, I took out my CAT almost 2 years ago when doing exhaust work and the CAT sat outside on the side of my house for quite a while. Now it is time for emissions soon so I need to put it back on. Should I just get a new one in case it got clogged? If so where can I get a good OEM CAT that will not throw any codes...which is what I'm worried about.
