Assembly of the ROUSH Off-Road Exhaust (422266)
The following section will guide you through the assembly and installation of the ROUSH components.
1. Loosen the rear spring support bracket bolt so that there is a gap of about 7-10 mm of threads showing.
2. Slide over the ange cut off during disassembly in this manual. Position the new catalyst pipe adapter ange
into place against the catalyst pipe and loosely install the two (2) takeout fasteners to hold it in place.
3. Position the new muer outlet axle pipe into position and install the steel hanger brackets into the factory
rubber hangers. Orient the pipe such that the ared end faces forward in vehicle. At this time, re-install the
hanger bracket that was removed in step 3 of the Disassembly section.
4. Insert one (1) 3" clamp over the outlet end of the new muer assembly and slide this into the end of the
muer outlet pipe. Position the clamp on the joint and loosely secure.
5. Remove the intermediate pipe and cut the pipe. Mark the pipe and double check BEFORE cutting to ensure it
will be cut correctly. Be sure to leave enough length for engagement into the catalyst pipe ange. Cut off the
end OPPOSITE the hanger that is welded to the pipe. Remove all sharp edges after cutting.
7. Re-install the pipe assembly to the catalyst ange. Loosely install the two (2) fasteners.
