Removal of Stock System:

the four bolt flange located behind the catalytic converter. If the vehicle is
not equipped with a catalytic converter disconnect the four bolt flange
located approximately under the passenger side seat. Refer to Figure 1. Do

2. Install the Extension Pipe into the Slip Joint placing the bend around,
under the cross member. Rotate the pipe to position the bend towards the
driveshaft. The Extension Pipe does not require cutting to fit Crew Cab
trucks. For extended cab trucks, approximately 9½” needs to be cut off the
end with the longest straight section of pipe. (Installation tip: Temporarily
hang the Muffler and the Passenger Side Tail Pipe in place and measure
to the four bolt flange to verify the length required).
