Under seat rear exhaust. Ram air intake. All maintenance kept up to date. Oil change recently done, with k&n oil filter. Coolant flush and replacement. Purchased from an older architect. Bike only has 9k miles. Super smooth, super fast ;) comes with battery tender and rear stand which makes oil changes , chain cleaning and lubing basically everything easier. This is not a starter friendly bike with a top speed of 180mph. Bike was dropped going 10mph, guess it was a little heavy for the older rider pffft. It had frame sliders so don't worry.
