I would like to put an aftermarket exhaust and an aftermarket air intake on my 03 wrangler. Any suggestions on what brands and models i should go with? I have considered going with a snorkel...any input would be greatly appreciated!!

You already have the best intake and exhaust you could need. Stick with your OEM setup...

double yep, save your coin. no performance increases that you will see or feel. that 10hp gain = big price tag.

Assuming your 03 TJ has a 4.0L 6Cyl just as my 06 TJ. I recently installed a bored & ported 63mm throttle body and gained at least 10-15hp from the 4.0L while spending $119. The mileage has not changed and now intake and exhaust mods can provide maximum gains. The stock TB only measured 52mm near the base restricting the entire aspiration of the intake/exhaust system. I previously owned a 97 TJ 4Cyl 2.5L and after performing many power mods to the engine the best bang for the buck hands down was swapping in a 4.0L throttle body!

How do you know you gained these extra ponies? Did you put it on a dyno before and after?
