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?

Thanx.

the FIPK system is a good improvment and a simple way to acheive increased performance. If money is a problem you can easily make your own by buying a filter, an adapter of some kind(i have Rusty's Air Tube), and making a heat sheild out of materials you can get at Lowe's.

For exhaust systems you really need to upgrade the whole thing to see any worthwile improvment. if you get just the headers then the air is still going to get "backed up" at the cat and muffler. a hi-flow cat will definitly be worth your time. if you want that nice sound a muffler (like the Flowmaster 50 series) will give it too you even with out the other stuff. but like i said with just changing one component the performance increase will not be very great.

If you decide to go for a chip it will give you solid results but for a price. gas mileage goes way down the tube.

hoped that helped just a little bit.
