Some performance questions...
I'm looking for a few performance upgrades for my Grand Cherokee ('98 4.0L I6). I have been looking around (at posts here, primarily), and have noticed that one of the most suggested/performed upgrades is installing a high-flow intake and a new exhaust manifold.
I'm considering getting a K&N FIPK system and a Banks stainless-steel header. Is this worthwhile? (And, what kind of power improvements do you think I'll see)
I was also thinking about getting a cat-back system, but am not entirely convinced it's worth it. The largest I could find for the I6 is 2.5" which doesn't seem like a big improvement over factory. Any suggestions? Also, I was thinking about a high flow cat, muffler (if I don't get the catback), and perhaps a chip...how does this sound?

I'd rather be driving a Zamboni...
