Installing the Cummins R2.8 in a four-wheel drive can be challenging, especially for applications with the front differential / driveshaft on the passenger side of the vehicle. The DOC exhaust filter (otherwise known as the round canister attached to the exhaust port of the turbo) is usually right where the front driveshaft or passenger frame rail needs to be.  The Quick Draw Brand R2.8 DOC remote flange allows the DOC filter to be positioned further down the exhaust system, freeing up valuable room in the engine bay.  The R2.8 DOC Remote Flange is machined from mild steel and is stepped down to 2.5″ exhaust pipe using a v band clamp. This simple solution provides greater flexibility for engine placement while remaining EPA compliant.  We also offer a mild steel or stainless steel flange separately that works with the  DOC’s 2 bolt flange that helps complete the exhaust system.

Kit Includes:

  • R2.8 DOC remote flange
  • 2.5″ stainless v band clamp
