This exhaust adapter fits S400/S410 turbos with marmon style exhaust flanges. This down pipe comes off the turbo and reduces down to 4" diameter for easy fabrication into your existing exhaust system.
Universal fitment for vehicle application, but commonly used on semi-truck to route exhaust straight back under the cab, above the frame rail.
If you have fitment questions, please email us - Info@momentumworx.com
*Turbine housing not included.
