If the dealer installs the tune, no. The ECM has to be retuned for the decreased backpressure in the exhaust. Triumph dealers have the standard re-tune available. If you later add the 5 filter K & N setup you'll need a remap as well. I ran the stock exhaust setup (just bypass) and it was much meatier (less Singer buttonhole model). The decel pop didn't arrive with a vengence until I went with the K & N setup. That Tuneboy resolved nicely. Good luck.
