Description
A down pipe for an S300 swap
This 3 in. down pipe is for LB7 Duramax trucks running an S300 turbo with an HX40-style exhaust outlet flange. It comes with a V-band clamp, heat wrap and clamps, and a high-temperature coating.
Wehrli built it for the ProFab 6.5 in. fabricated pedestal. Other pedestals may work but are not verified; the pedestal must be 5-6 in. tall.
The lower flange meets the factory exhaust flange and uses the factory V-band clamp, so it installs easily.
Who it's for
LB7 owners installing an S300 single turbo.
