Yep, that's the one! I'm in Canada and the shipping took about a month and cost R$230 (That is Brazilian real's). I don't know how different it would be to the UK, but I'm guessing not that far off. Overall I am super happy with the sound, looks, and quality of the muffler and would definitely recommend it to anyone interested in getting it. One note I will make is it does not have a catalytic converter, which can be illegal in some places, although no one would ever be able to know without doing a full inspection of the bike.
I went for the Akra race exhaust which doesn’t have the cat in either , i don’t believe they are checked in the U.K. MOT ( or at least I hope not ) I would love to see and hear one of these up close and was toying with the idea when I was looking , but for me it was too much of a risk to order one not knowing anyone else who had one , I thought perhaps the engine may need re mapping etc .
