my 01 4.0 is louder than my buddys 01 4.0. i'm not talking exhaust right now either....both idling in a parking lot, mine is noticeably louder running when standing in front of them.

That white puff of smoke is nos. I`m not over 400hp, that was nicksters old set-up I believe. The closest I got was 360hp and 417tq. Kept pegging the maf (gt maf w/t ee kit) so Doug had to back it down to 333hp and 370tq. Plus, Doug would`nt let me leave the dyno making 360 on a stock motor. Something about leaving engine parts all the way up I-20 to SC.

Sounds like it could be one of your engines accessories water pump, fan clutch, tensioner, idler pulley or alternator could be making noise. Pull your belt off and run the engine for a minute see if the noise goes away if it does it is one or maybe two of the accessories. Spin each one to see which is the culprit.
