Huron Speed Truck T4 4" Downpipe for 1.25 Housings

Huron Speed 4" Downpipe for Truck T4 kit 

-This downpipe is an optional 4" downpipe to replace the 3" downpipe in our Truck T4 kit.

-Downpipe still recirculates the wastegates

-Designed to bolt to T4 S400 turbos and the VSR 7875 1.25 housing turbo.

-Designed on a 2009-13 truck, with that in mind you may need to tweak for fitment through the frame on a 99-08 truck as the 4" takes up nearly all of the space and the frames are slightly different.
