The following images depict the typical exhaust routings for each system, and can be used to determine exhaust routing<br />
paths for systems you choose. Dimensional information can be found in Section 5 of this manual.<br />
<strong>Body</strong> <strong>Builder</strong>s must not modify (including altering, substituting, and relocating) the DPF and SCR canisters. The exhaust<br />
