RAPID FLOW INSTALLATION
Rapid Flow Exhaust # 81222
13. 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. 
14.  Once the entire exhaust system is installed, in-
spect the system to ensure that no part of the ex-
haust is in direct contact with the chassis or body; 
adjustments may be necessary.
16.  Return  to  each  of  the  Clamps  and 
tighten with a 9/16” wrench. 
17. Stainless Steel Tips are available from Bully Dog 
to give your truck that polished, classy, look.
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.
