just got back from north ga powersports. had my stage 1 flash done and went ahead and had them install the vic high flow air filter. it was between mountain motorsports, tommys in Crossville, and north ga where to get it done. all are about 1-1/2 hrs away. I had trouble getting ahold of tommys, and the people at north ga were just nicer, so I went there. they did a good job for a good price, and even sold me some passenger floorboards for a price I couldn't pass up. the bike runs a lot smoother now, and more power, but i'm more impressed with the smoothness. it doesn't pop any more now than when it just had the cherry bombs with no filter or pipes. it does pop pretty good when you are getting on it and shifting fast, but no more or less than before. overall I am very happy with it, now to go out and install the floorboards.
