warranty question on exhausts

[jjolin]

Has anybody had a problem with the warranty when UP grading to a 4" exhaust?

Never heard of it being an issue on any truck of any type/kind before. It more depends on the Dealer and how staunchy they are. It is of course a Federal infraction to alter and or replace the exhaust system with anything louder than stock. Of course, NO ONE on this site would ever consider doing such a thing!
