I have the V&H Basics and PCIII (although on a 2006 model). I am very pleased and would buy again. They offer a great sound and look IMO. I used the slip on with the stock head pipes for about 6 months, then put on the V&H duals. A slight bit louder than I would like, but nothing obnoxious.
Just ordered V&H Big Shot True Duals, Arlen Ness Stage 1, Fuel Moto PCIII.
Should be in and on by next week, I will report!
Just to let you know I run the V&H Big Shots and a friend of mine has the V&H Basics the Big Shots are quite a bit louder than the Basics, but not overly.
