I ordered a walker muffler #22572 today and was wondering where the best place to mount the muffler would be. I currently have removed the resonator and the stock muffler and replaced them with a Dynomax Ultra Flo. I mounted the ultra flo where the resonator was and it was fine for the past year but now I have a terrible drone in the cab, plus I am ready for something different. Should I mount it where the ultra flo is or move it back towards the tail like the stock muffler used to be. Any thoughts would be appreciated.
