Exit Option:  Most fendered vehicle applications do not have provisions for an under-chassis exhaust because the fenders and running boards are in the way. However, some crafters have modified their vehicles with an access provision to route a downpipe. For this reason, the default Jayster Full Fender does NOT include an under-chassis adapter. However, it is available when needed.
