Rerouting Exhaust on TRD Off Road

Has anyone extended their Tacoma's exhaust pipe to the corner of the bed where the fender meets the bumper finishing off the rerouting with an angle cut stainless tip? I have had an ongoing problem (three white Tacomas) with dust and exhaust vapor staining the right rear fender behind the mudflap https://www.tacomaworld.com/threads/exhaust-stain-on-rear-fender.299941/

Sure would appreciate a pic of such an installation before I head to a muffler/exhaust shop.

 

Do you do a lot of idling?

 

Hardly any idling. The Tacomas are my wife daily drivers. She puts over 20,000 miles per year on her trucks. Her trucks don't get a chance to idle. Most of the driving is at highway speeds.
