The following images depict the typical exhaust routings for each system, and can be used to determine exhaust routing
paths for systems you choose . Dimensional information can be found in Section 5 of this manual .
Body Builders must not modify (including altering, substituting, and relocating) the DPF and SCR canisters . The exhaust
piping after it exits the SCR canister may be modified, however using smaller diameter piping or piping with numerous
bends is not recommend as the backpressure requirements of the system may be exceeded .
