Valve Assembly Installation
Inspect the vehicles exhaust system between the engine and the muffler. A straight
section of pipe will have to be cut to accommodate the exhaust brake assembly -
approximately 7 to 8 inches long. On 1994 or newer Dodges, the valve is mounted
before the Catalytic Converter, on Ford and Chev/GM vehicles with Catalytic
Converters, the valve is mounted between the Cat and muffler.
There should be no exhaust-flex pipe between the engine and exhaust brake valve,
however, flex pipe is okay after the valve. Cut the exhaust pipe in a straight section of
the system, you will need to weld one of the supplied adapters to the section of pipe
coming from the front of the vehicle's engine.
Temporarily mount the exhaust valve assembly on the adapter, with the supplied V
clamp on the valve sliding. From here, cut off as much of the remaining exhaust
needed to accommodate the valve and remaining adapter. Remove the exhaust valve
assembly and clamp, or weld the rear adapter to the other section of exhaust pipe.
Mount the exhaust valve assembly using the two supplied V-clamps, with the vacuum
cylinder pointing away from the engine, and tighten the nuts and bolts.
NOTE: The arrow on the Exhaust Valve casting indicates exhaust flow, which
should be pointed towards the rear of the vehicle (Figure 1).
