6.7L Cummins · 2013–2018 · 4 inch mandrel bent
TIG-welded 304 stainless, mandrel bent, and flanged to match the factory outlet without adapters.
Part number SSD-DP-6713
$299.00
A restrictive downpipe costs you exhaust flow and raises EGT. This one is mandrel bent so the diameter stays consistent through every bend, and TIG welded in 304 stainless so it does not rust out.
This is a direct replacement for the factory downpipe and bolts to the factory emissions components downstream. All factory emissions hardware stays in place — we do not sell or install delete parts.
