I got the DW Holeshort header installed today. Very straight forward, and found a trick so the rad doesn't have to be removed. Going to hang the mufflers tomorrow and test run. There is a definite weight savings over the stock system. The install goes fairly easy since the new header is a two piece affair instead of the one piece stock system. Finish is up to the normal Holeshot standards as well. I've done the metallic ceramic coating previously on my atv pipe and the header on my pick-up. Very pleased with each.
