Nice Exhaust Pixy Flash,
I bid on a pair of scorpion back boxes earlier this year which i won and they have made a nice difference to the exhaust note but not as much as i would like. Once out of warranty will look at having Y piece and centre pipe manufactured but still feel the silencers are over large ( the original back boxes are huge as you know). would you please keep the forum updated with feedback, video and sound clips if you can.
Cheers
AJZ
