yeah, don't get the regular 40's... you want to get the Super 40's....

I have the super 40's on mine... sounds fricken awesome... sorry, no vid/sound clips tho...

but, they have a nice deep rumble at idle... and nice growl when you get on it... vibrates the garage side of my house when I pull in hehe...


and all I did was change mufflers... the rest is still all stock...

nope, not raspy at all... and loud?? well, they make more noise than stock, but they're not LOUD inside... I can still listen to the radio at normal low volumes and hear it just fine...

louder than stock? yes... REAL loud or TOO loud?? no... like I said, I only replaced the mufflers... all the rest of the pipe, resonator, etc is all stock and still there...

dont get all hasty now ... im trying to save you some money, allow me to make a new video of my car when its not pitch black out and since the mufflers have broken in a bit since my first video ...

ill get it up for you this weekend, because i need to get a video of my system as well ... now i got 2 reasons to bust out the camera

whatever you end up doing, cut the resonator out, its barely noticeable at cruising speeds with the stock radio at minimal listening volume, and around town with the radio off and the windows down ... not quite straight pipe, but then again chicago area cops dont need another reason to light you up
