Yes the EPA emission tested exhaust is for getting it inspected those pesky rules.Besides,not to mention it's nice and Quite.AAAHHHH!anyway,. Xtremelow has a good point.Nice and easy to remove and put an Aftermarket exhaust on.I really wish I could buy one Real Soon!Black and Blue with a flicker of Ghostblue & white flames on it.Got to admit People we all know if Erik went into Business Tomorrow He would never get caught up from the orders for American Sportbikes.At least for a while! The Valves are Titanium and the heads have been reworked Many other goodies as well.No easy payment plan for that Ride!![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
