Hello! Just joined this site! So far I am impressed! I have a 2002 Chevy HUD Crew Cab Short Bed. EFi live with DP5 switch. Air horn mod. Air box mod. 4" MBRP with no muffler and 5" tip. I love my truck and I got it very cheap! Makes it even better! I am an Auto shop teacher here in NH and the kids love to work on my truck as much as I do. Cant wait to learn as much as possible here. Can never learn to much right!
