I had one fitted for a Moto Guzzi Griso I used to own. Great looks and sound and very well made. - except it is an open pipe and I needed a power commander to fix my fueling. Not sure how this will work on the scrambler.
I emailed one of the sellers, Bignose Racing. David replied saying the exhaust is intended to be plug and play with no remap required. He also said it has just been released with little info online as of yet. I did find the GPR website but I don't think I see that particular pipe.
