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 2500's 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.
