a body chrome exhaust tip?

Just the one resonator tip for my 273 commando package costs more than a pair of those dual exhaust tips. The commando package is being gathered for one car and dual exhaust is going in another car meaning I need all 3 parts. Counting coins ? We all do it. We should count or blessings so often.
On a single exhaust car with tube turn down only, Anyone ever noticed the reverse lamp fixture on the left corrodes and pits worse than the right side fixture ? Would a straight away tip would make a difference there ?
