During my decision process, the dealer argued that I should also change the entire pipe from the head to the can, claiming that is where I would experience the peak performance improvement. I graciously declined, as I wanted to see if there was any difference with just the can, first.
Difference? Well, it sounds more like a motorcycle, I guess. Performance? Really hard to tell. I guess I am saying ... I don't see any difference. But, then again, I am a granny-rider.
I'd trust a dynamometer for rear wheel horsepower/torque to see if there was a difference. Frankly, though, I doubt there is much. Unfortunately, I have not found a MC shop with a dynamometer in town.
