Well I wanted the new Harley type system dual out behind the tire on the right side. But it is not released yet, so I went with my second choice which was the Lightening style, dual out in front of the tire. The directions were vague, and there was NO detail on where to install the added hanger. Luckily I have some mechanical experience so it was figured out easily. The last complaint is that the add on hanger was nearly too short. Otherwise the hardest part is removing the old exhaust. I did the whole thing myself with a total of four tools in about 30 minutes. The sound is good, and is not too loud at cruise. Overall
