Not bad! How much of a performance gain did the cold air intake and free flow exhaust offer? ...and how did it effect your fuel economy?
I did a similar mod to my GMC Denali... yes, it sounded beefier. Not sure if performance increased at all, but the fuel economy got worse... ( maybe because I liked the sound ? )
