Hey guys. I have found very little info on this system online so I figured I would share my experience so far. The system showed up to my house last Friday and I have it mounted but have not had a chance to ride it yet. The packaging was great. The finish on these parts is amazing as well. Ever since I had laid eyes on the Bill's system I have wanted it. I really did not want to be another dude on a Honda with a Yoshi. The price is great for what you are getting as well. I did not weigh them compared to stock as I had no means of doing it but holding the Bill's parts vs stock in my hands they seemed about the same with the Bill's maybe being slightly lighter. This system fit better than stock! the fit is absolutely amazing! No fighting it, no leaving everything loose to try and pull it in 5 different directions once the bolts are started, it just slipped right together and bolted up. It gave the bike a great tone, its nice and deep and it no longer sounds like a beefed up 250. I was busy all weekend so I am hoping to get out and test ride tonight or tomorrow and then I will update my results. Here are some pics I took of unboxing and some stock comparison pics. Enjoy!
