Yeah I called DAP last week. They said they would check the wearhouse and call me back. Never called back. But i emailed in and they said I need a HX35-HE351 Adapter Sweet! It goes from 3" to 4 3/8" Awesome!
New to this forum, but not the cummins forum. I bought this truck a month ago, turbo bearings are shot. I bought a Borg Warner K27 turbo. Truck is set up with a 4 inch down pipe with an HX40 4 3/8" Flange. I need an adapter to go from 3" inch ( stock size ) up to the 4 3/8" flange. I've called several diesel specialty shops. No luck.
