How can I disguise white exhaust pipes coming out the front of my semi. Can they be painted to blend in with the brick? Any other suggestions on how to disguise these eyesore.

Lot depends on their material and what temperatures they experience as to if that can be effectively done and last.

I will assume these are the intake and exhaust pipes for a condensing furnace?? I painted mine to match our log home. Use a plastic promer first as they are most likely PVC.
