2001 dodge ram 2500 4x4 5.9l gas by bman, September 6, 2013

Ease of Use/Installation:
Overall Rating:

over all these headers are good. the drivers side took the longest time do to the lack of space for the bolts. I can feel the difference when Im towing. The sound is a little different from stock......but have not got the whole system yet.....
