Revised Y-Pipe: Now works with 4L60E & 4L80E transmissions. Also allows more room for 4wd vehicles.
Note: If using a larger 4L80E transmission, the bellhousing ears may need to be trimmed for proper clearance.
Note: Earlier 2500s might have fitment issues due to chassis being designed from previous years.
Note: Most 6.0 applications have a 2-into-1 exhaust system which our y-pipe system will not work with. Double check your exhaust for confirmation of fitment with single exhaust. Our x-pipe kit can work on the 2-into-1 exhaust systems but require fabrication for connection.
