Exhaust was easy to install and sounds great. It really lets loose the V-four that was couped up from the stock exhaust. My only complaints were that it didn't come with the silicone red RTV for the joints so I went and bought some. It also didn't come with any installations instructions so I had to watch some youtube videos to make sure I was doing everything correctly. Either than that, it makes me way more excited to go take my bike for a spin. Solid pipes!
