1964 Valiant - Protective plate for fenderwell headers? Pic inside

I have the same car, same fenderwell headers, just as low, yet my pipes come straight back from the headers, under the rear housing right to the rear bumper where you'll find SuperTrapps.. No problems in 25 years of driving. Although the car and exhaust is low, as long as we don't drive like assholes, everything works well...
