Hey guys, So i finally installed a Leo Vince GP Pro II on my 2010 fireblade. Really happy with it, it sounds amazing, deep & growling at low rpm's & it screams up top. Also happy with the performance gains, bike pulls much harder now. Idle's great as well so no need for a power commander yet (i've got a U.S spec bike which doesn't have a 02 sensor). Here are some pics, yes i know i need to get rid of the hideous fender: And here's a video, will try & make a proper fly-by one soon: https://www.facebook.com/photo.php?v=10151233073910299
