I got my Leo Vince titanium pipe yesterday and took it out for a run today. I like it! I was running a Holeshot high mount recently. I now have ridden the bandit with the following setups:
Bone stock - Nice smooth torque and quiet
Holeshot 14" low mount/no jet kit - Definitely louder and has a distinct throaty sound. It also gives a bit more power on the top end
Holeshot 14" high mount w/jet kit - Quicker throttle reponse and about 11hp/4 ft lbs of torque increase with a drop of about 7 lbs weight.
Viper pipe bolt on - Nice pipe and inexpensive - more mid range and gives it an almost stock look, but free flowing.
Leo Vince SBK titanium w/ jet kit- Nice sound and a bit deeper than my Hole shot. It always feels like I got more torque than with my Hole shot. With stock gearing, my front end comes up a bit easier and did it to me twice today. It also looks better with the stock header as well. You don't have the two color changes. In the past, I wouldn't have considered Leo Vince, but since I got such a good deal on Ebay, I went for it. I must say that I am thouroughly impressed with the finish, looks, and power with the slip on. I will be taking pics of it tomorrow and posting them.
