A while back I decided to go Stage 2 on my '17 TG. H-D air cleaner, Woods 222 cam, de-catted pipe and Rinehart mufflers. It was tuned after all work was done. The mufflers are somewhat louder than stock and it has been fun cranking it up, but I am ready to quiet back down. I have the stock mufflers and am looking at changing back to them. I know that I may lose a little power. Will I need to do another tune? Not looking to buy another pair of mufflers.
