Honda CB400 Super Four VTEC - IXIL Slip-On Exhaust

My Facebook Page - The bike is a 2013 Honda CB400 Super Four Hyper VTEC Revo. The original exhaust (which sounded terrible and was huge) was replaced with this IXIL Slip-On Exhaust with no baffle. It makes the bike really loud and as there is no baffle, the bike runs a little lean, hence the little bit of backfire when downshifting and decelerating. The bike is loud is the low RPM, but nothing crazy, but when it reaches VTEC, that's when it opens up and sounds amazing
