Nice Headers Great price by Sportster, July 9, 2014

Ease of Use/Installation:
Overall Rating:

2005 Silverado 2500HD 6.0L Ceramic coated header install was easy once stock exhaust was removed. Not much change in tone with stock exhaust cat-back. Did notice increased acceleration. That in itself worth the $. Drove a few hundred miles retorqued the bolts (no change) and no discoloration. I m liking them!
