I have a stage 3 setup on my 2016 Chieftain. I have the Indian Stage 1 pipes, Big air cleaner and find them a little louder than I like these days. Would putting the stock mufflers back on impede performance? I have been told that the stock muffler would not inhibit the exhaust gas velocity or restrict volume sufficiently to create a performance decrease and then have heard the contrary as well. Anyone have an informed opinion on this exercise?
