Installed and soundin' SWEEEEEET!!! It isn't too loud and the sound is deep and sweet!!! Performance, I started feeling an increase in HP around 10 miles of driving on it and it keeps getting better!~OH YEAH, Scared the **** out of myself! When I started it for the first time I took it for a rip around town and when I came flying back up into my lot smoke was pouring off of it. Then my step-dad told me that it's the chrome and finish burning off. Either way it stopped and everything's better. Installation was Easy (except it took 1.5 hours, one of which was removing ONE stubborn bolt on the CAT frange) I took pics, I'll get them developed tomorrow, scan them, and post, them. Till then, GET SUM'!!!!
