they may help to some small extent, it really all depends how far the tip sits away from the end of the bumper. the FD has more problems with this than most because the end cap curves out after the muffler.

best method is to just tune it properly with either lean decel or decel fuel cut and do not allow the muffler tip to touch the bumper skin/guard.

a few fireballs on the freeway after some pulls won't hurt anything.
