DHD 300-324 3" Stainless Tube LLY LBZ LMM Duramax Downpipe w/Heat Wrap

DHD Duramax Turbocharger Performance Downpipes

Get rid of that ugly restrictive downpipe and replace it with our 3" Stainless downpipe w/heat wrap. 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. Our downpipe has mandrel bent corners and welds only at the flanges not in the middle of the pipe like other brands. Flanges are machined and zinc coated, not cast.

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