the mopar setup IS LOUD. sounds real mean & very wicked. i just had the mopar race midpipe & exhaust. stock headers. some drone. it would aggrevate me (the drone) on long trips. my 05 was a daily driver & while i loved the setup @ first, the 1500 or so miles that i put on it every month started to make me appreciate the corsa setup that i previously had. the corsa had a slightly more aggresive note than stock, but not nearly as throaty as the mopar. however, the corsa was sooo much easier to live with.
i bought the mopar race computer to deal w/the o2 sensor issue. but then my AC would sporadically turn off. i guess the reasoning there is that race cars don't have AC?!?
bottom line, in my opinion, the mopar is bad a$$ sounding, but very loud. i don't suggest it to be placed on a car that is destined to be a daily driver. my passengers would often complain about the noise lvl. hard to hold a conversation. i'm sure some won't mind how loud it is, but i'd imagine it would bother most. hell, i know it would bother most. a 2 - 3 hundred mile trip w/those cans can't be good for your hearing.
however, if your car is just a weekend toy & you want it to sound loud & angry, then put em on.
