DHD Duramax Turbocharger Performance Downpipes

Get rid of that ugly restrictive downpipe and replace it with our 3" Stainless downpipe w/heat wrapping which creates better flow making "MO POWA BABY." Our downpipe provides a smooth and consistent 3" bore throughout the entire length of the pipe which equates to better CFM flow over the stock down-pipe.

Note: A few washers may be needed to shim the dipstick tube from the down pipe.
