They worked and sound great pick up my 1/8 mile speed 1 mile per hour to 84 mph not bad for a 5900lb truck ! Gain about 20 hp just changing to JBA headers.

The overall system looks very good and all welds are top quality. The rear hanger does not exactly line up with the hanger on my 2003 GMC pickup, but we made it work. The system has a very nice, low sound and is not overly loud. The one I installed had a tinny rattle at idle, but I was able to get it out by moving the tailpipe a bit further inboard. Overall, good buy and thus far I am very pleased with it.
