everyone i know that has the skunk 2 their car is still loud. i dont know if you care anymore since you will probably be getting a daily driver when you get back but that's my .02, i have been doing research on these systems for my subaru
http://www.jhpusa.com/store/pc/viewC...ory=354&page=2 and they are decently priced and you can go on youtube and listen to the sound clips (for a subaru anyways) and they are pretty grumbly sounding (meaning low, deep tone)
and didnt scotty say you needed a 3 inch exhaust or 2 1/2??
