I have a car in being painted so riding the ttr it's way too loud with the staintune pipe for the hospital car park where I work . Just remembered I have the original muffler that was taken off by the dealer before it hit the road . Might make it more acceptable next week
Having just changed mine back to the original, I can say it's much quieter. Probably good for around town etc, but I miss the throaty growl of the after market.
