9. At this point it is time to install the other Straight
Pipe. You will need to measure the Straight 
Pipe to the correct length, keeping in mind 
that you will need to have an extra 3 inches of 
overlap when you cut the pipe. 
10. Once the entire exhaust system is installed, in-
spect the system to ensure that no part of the 
exhaust is in direct contact with the chassis or 
body; adjustments may be necessary.
11. Return to each of the Clamps and tighten
with a 9/16” wrench. Again, do not over 
tighten Clamps. Having any part of the ex-
haust system in direct contact with any part of 
the body or chassis will the cause the exhaust 
to rattle. 
IMpoRTaNT: Do not over-tighten clamps. Too much torque will result in deformation of the exhaust. For best results 
when doing the installation, tighten the clamps enough to hold the exhaust pieces in place, but don’t tighten down 
until the entire exhaust system is installed.
