17. Place 2-1/2” clamps on the X-pipe or Y-pipe as provided in your kit and slide
onto the leadpipes. The X-pipe or Y-pipe will not sit exactly level for a proper
installation. The picture below shows the X-pipe properly positioned from the
rear of the truck. The Y-pipe connects to the lead pipes exactly as the X-pipe.
18. If installing to factory exhaust, using OEM clamp, install clamp on Y-pipe and
tighten all three clamps. If also installing the Stainless Works Dual Exhaust, see
those Installation Instructions at this time.
19. Be sure to have adequate clearance around all wires, hoses and lines. If anything
is in contact with the exhaust system, it will melt. Make sure to have at least
½” of clearance and wrap any suspect areas with DEI thermal barrier wrap.
20. After double checking for clearance and making sure all lines, wires and hoses are
secured, drive the car for 10-20 miles and re-check all clamps and clearances.
