Jet 7?

[Janne]

Have a 98 V-Max, European model that I want to get more power from.   I understand  that Dyno Jet, Stage 7 is the way to do it. In this kit I also understand I have to include new filters and new exhaust.   My question and concern is if I can  with a choise of jets effect the charactheristics of the engine? I want a flat tourqe curve.   Second, when I change the exhaust I will have a better sound, but I don't want to get ride of the possibility to use central stand. I also prefer to have two pipes (think it looks great). What choise do I have on the market?    Has slip on any negative effect compared to a completly new system ?   Any other good advices or recommendations how to do this, most probably I will ask a dealer / workshop to do the operation.   Cost proposal a got was approx 10-13000 Swedish, equal to 1500 USD.   Rgds Janne
