X2 on Pznivy's focus on WEIGHT.

If you don't want to gear, you should stick with keeping the weight down. These air flow mods will make your stock jeep nicer to drive, but will not save you from the performance decrease you should expect if you do steel bumpers, flares, etc.

If you were asking me about what sort of overall plan you should try for and NOT change those 3.21s, Id say your pretty much there. 33s. Stock bumpers, no winch. A stock jeep looks beautiful, and without the extra weight, yours will perform better than stock with the air flow pieces your talking about.

Intake first is the rule, if you can, drive it like that for a week. THEN do the exhaust. I like listening to the engine better than listening to the exhaust. Keep the stock exhaust on and do the intake and you will see what I mean. Then do the exhaust after, and keep the option in your pocket to go back to stock if you feel like it.
