INSTRUCTIONS:
NOTE: do not tighten any clamps or nuts and bolts until the last step!! Before cutting any pipes it is a good idea to lay out all the included pipes along side the vehicle and get a good idea of how the pipes will hang on the vehicle. Please read the instructions fully and thoroughly before you begin.
1)
2) Install the left tail pipe (4 bends) using a 2-1/4” clamp, making sure that you have clearance between the rear brake line (bend bracket to the front if necessary), shock, and spare tire. The left tail pipe crosses over the top of the drive shaft and then crosses over the top of the axle. Install the 2-1/4” hanger clamp to the O.E. rubber hanger mount above the first bend in the left tail pipe, and clamp to the left tail pipe. It will be necessary to gain the proper clearance between the left tail pipe and the brake and breather lines by tying the lines away using a wire or cable tie. You may want to trim the pipe to length, so do not tighten the clamp yet.
3) Locate or drill a 5/16” hole in the frame after the last bend in the left tail pipe and install a BR91930 swinger hanger to the frame using a 5/16” x 1” bolt, nut, lock washer, and fender washer. Clamp the hanger to the left tail pipe using a 2-1/4” clamp.
4) Install the right tail pipe (it has 5 bends) to the y-pipe using a 2-1/4” clamp and making sure that you have at least 1/2” of clearance from the shock. Do not tighten the clamp at this time.
5) Repeat Step 4) for the right tail pipe.
6) Trim your tail pipes as necessary. Hold up a tip to a tail pipe and mark the length to cut off. Mount the muffler tips to the tail pipes using a 2-1/4” clamps.
7) Tighten all clamps, nuts, and bolts. Check for leaks and for clearance of all brake and fuel lines, and for clearance of all chassis and frame components. We recommend tack welding the joints (not necessary though).
