10. Route the tailpipe such that it is not likely to be<br />
struck when the vehicle is moving. Keep it out<br />
of the approach and departure angles of the vehicle<br />
and above the axle clearance line (Figure<br />
3-6).<br />
11. Make sure a tail pipe deflector will not cause excessive<br />
back pressure or interfere with removing<br />
a spark arresting screen, if so equipped.<br />
CAUTION Excessive back pressure can<br />
cause loss of performance and engine damage.<br />
12. Unless the muffler has an integral spark arrestor,<br />
install a spark screen (Figure 3-7) or other<br />
kind of approved add-on device to comply with<br />
regulations for vehicles driven on federal lands.<br />
