My exhaust, well the muffler portion, is burning up my bumper. Can you push the exhaust further out while installed? Or will I have to uninstall it and move it that way?

 

Get yourself a snazzy muffler tip that sticks out further than what you have now.

 

if you know how to weld then weld on how ever long of extra piping needed on the axel back to set the muffler where you want it and dont forget about the hangers too or go to a exaust shop and they will do it for pretty cheap.
