Section 3, Installing the Exhaust System 

band clamps are recommended for joining flex and solid 
tubing as they apply firm, even pressure.  

•

 

In a coach, install an exhaust collar on the exhaust pipe to 

isolate the pipe from the coach frame.  This reduces vibration 
and noise and protects the coach from the effects of high 
exhaust temperature, see Figure 3-1:  Installing the Exhaust 
system (Bottom Exhaust).
