FITS 1988-1993 GM PICKUPS WITH 350 C.I. MOTOR AND 3" EXHAUST
NOTE:    DO NOT TIGHTEN ANY CLAMPS UNTIL THE LAST STEP!

1)    REMOVE THE SPARE TIRE FROM UNDER THE TRUCK.  BECAUSE OF CLEARANCE
PROBLEMS, YOU WILL NOT BE ABLE TO RUN THIS SYSTEM WITH THE SPARE TIRE IN
ITS ORIGINAL POSITION.  THEREFORE IT MUST BE PULLED PERMANENTLY!!!

2)    REMOVE THE EXHAUST SYSTEM LEAVING ONLY THE ORIGINAL Y PIPE AND CATALYTIC CONVERTER ON THE TRUCK.

NOTE:    THE EXTENSION PIPE WILL FIT THE LONGER WHEEL BASE TRUCKS WITHOUT
CUTTING.  ON ALL OTHER VEHICLES THE EXTENSION PIPE WILL NEED TO BE CUT FROM
THE 3" O.D. END (THE END THAT IS NOT EXPANDED) AS NECESSARY.  THE S-PORTION OF THE FRONT PIPE SHOULD SHIFT THE EXHAUST TOWARDS THE PASSENGER SIDE (SEE PICTURE).

3)    SLIP THE FRONT PIPE INTO PLACE.  WITH THE TAIL PIPES IN THE REAR OF THE
MUFFLER, HOLD UP THE MUFFLER AND TAIL PIPES IN A POSITION THAT CLEARS ALL
CHASSIS COMPONENTS.  MARK THE FRONT PIPE.  MAKE SURE TO ACCOUNT FOR AT
LEAST 2" OF THE PIPE TO GO INTO THE MUFFLER.  CUT THE FRONT PIPE.

4)    USE A 3" CLAMP TO ATTACH THE EXTENSION PIPE TO THE CATALYTIC CONVERTER.

5)    USE A 3" CLAMP TO ATTACH THE MUFFLER (#6842 OR EQUIVALENT) TO THE EXTENSION PIPE.

6)    SLIP THE RIGHT AND LEFT OVER THE AXEL PIPES INTO MUFFLER.

7)    WITH THE MUFFLER AND OVER THE AXEL PIPES IN PLACE, INSTALL THE TWO THU900
HANGERS ABOVE THE OUTLETS OF THE MUFFLER TO THE FRAME.  NOTE: IT MAY BE NECESSARY TO DRILL 5/16" HOLES IN THE FRAME IF THERE ARE NO HOLES PRESENT.  USE 5/16” X 1” BOLTS, NUTS, LOCK WASHERS, AND FENDER WASHERS TO CONNECT THE HANGERS TO THE FRAME.

8)    MOUNT THE MUFFLER AND TAIL PIPES TO THE HANGERS USING THE 3" CLAMPS (ONE FOR EACH OUTLET OF THE MUFFLER).

9)    INSTALL THE 28" LONG 3" I.D./O.D. TAIL PIPE EXTENSIONS TO THE OVER THE AXEL PIPES.

10)    LOCATE MOUNTING HOLES IN THE FRAME NEAR THE END OF THE OVER THE AXEL
SECTIONS OF THE TAIL PIPES.  IF NO MOUNTING HOLES ARE PRESENT, DRILL A 5/16" HOLE
IN THE FRAME FOR EACH TAIL PIPE.  INSTALL THE REMAINING THU900 HANGERS USING
THE FENDER WASHERS, NUTS, BOLTS AND LOCK WASHERS.  CLAMP THE HANGERS TO
THE REAR TAIL PIPE EXTENSIONS, CONNECTING THE TWO PIPES AND THE HANGERS.

11)    TRIM TAIL PIPES TO YOUR DESIRED LENGTHS.
