**While a downpipe is not included in this kit, we do include a machined exhaust adapter/reducer which v-band clamps onto the exhaust outlet of the S400 turbo, so that a 4” or 5” exhaust pipe can be welded or v-band clamped onto it. This makes it very convenient to attach whatever exhaust system you have to your cummins swap. We do offer a 2nd gen Dodge downpipe which will be close but made need adjustments to fit the Conversion projects.

Please Note: Chevy/Cummins or any other conversion kit are considered a custom application. The hardest part of these conversion kits are getting both turbos to fit in the truck and clear the heater core. Our compound kits are specifically designed to get both turbos to fit nicely. In most cases the intercooler hose will fit to a factory intercooler, and will allow the intake to fit as well, however because all of these conversion kits are so custom in nature it is the responsibility of the installer to tie in the intercooler, exhaust and intake tubing into the truck. This is because the engines, alternators, batteries, intercoolers, etc. can be done in some many different configurations it would be impossible for any single kit to universally fit every swap application. In most of the conversion applications, expect to do some fabricating to exhaust pipe, intake and/or intercooler tubing.
