You have fitted an awful lot of kit and so I would suggest that you take it to a rolling road (Dyno) and get the bike set up properly. It will csot you , but it will be well worth the money.

No it will not. You probably don't NEED to rejet at all. If the manufacturer suggests it for your bike and pipe combination I would follow their advice. If they do not suggest it I would use a dyno to get the best performance from your new setup. Keep in mine your new exhaust only lowers the back pressure. You haven't changed the intake parameters at all as far as airflow. So any additional air going into the cylinders due to your new exhaust will only be because of the reduced volume in the cylinder while the intake valve is open. This is a rather small amount, so don't get all crazy and jump several jet sizes at once.

I need to know if i have to re jet my 98 yamaha 650 v star if i put on the vance and hines cruzer exhaust just the exhaust nothing else. and also what type and size of jets to use


You can try driving the bike after the install. After you change the exhaust it will run lean. You may want to coat the inside of the mufflers with an anti blu-ing agent or your headers will discolor. If when test driving you notice the bike has developed a flat spot in the acceleration curve you will want to re-jet the carburetors. The easiest way is to buy a jet kit from Cobra, Dyna-jet,etc.($80-$100). Other wise you can just buy several sets of larger jets and change them out till you are happy with the way it runs. Most people that change the mufflers and put in a jet kit, also install a K&N air filter .
More air flow + fuel flow = more exhaust flow (more power)

Whats the best after market slip on pipe for both power increase and a nice sound...i have been looking at a very reasonably priced Vance and Hines S4 for just $249?


Vance and hines is always a good choice of pipe, the nice thing about vance and hines is that you can back out the hex bolts on the back of the muffler and repack it when it gets old, or unpack it if you want it louader. Makes it quite tunable. I had a vance and hines 4-1 on my CBR 1000 and I was very satified. The price you are mentioned is good too. The V&E I had on my bike had a good sound at idle and rev and sounded awesome when I tached the bike up.
