For all Chevy/GMC truck owners looking to increase their Horsepower
 

All GMC/Sierra truck owners should check out SLP's products at SLPonline.com I am just a customer of theirs and I think they have quality products and service. They are a little bit more expensive but thats because they only sell the best stuff. So far from them I have their programmer and their exhaust on my 2003 2500HD Sierra...Although their exhaust didnt fit perfect because it wasnt designed for the HD style, it was easily fixable...Their programmer does help a lot. I am hoping to get their headers soon so i will let you all know about them and how they work for me.
