AJ When I said go with what you like I meant what looks appealing as far as look's. You'll get about the same result's from any of the intakes. Doing the intake without doing the exhaust is a waste of time in my opinion. If anything do the exhaust first. As far as jet kit's, the dynojet kit has only the adjustable needle in it that is useable, like I said before you'll need a 50 primary because the vulcan's are know to run lean ( to pass epa standards). The 165 or 170 main is what you'll need if an when you do the intake.If you do just the pipes you don't need to rejet, just back the air/fuel mixture screw out a 1/2 to 3/4 of a turn.The stock needle won't work when you put the 50 primary in, You'll need an adjustable needle so you can adjust the setting's, on how deep it seat's into the new 50 primary. Are you confussed yet? As far as gutting the stock pipes, all you have done is make them louder because the main pipe inside the muffler is still restricted from the small size that it is. When you do the intake you might as well remove the epa crap. The bike will run a little cooler an some of the popping on decelaration will be gone. If I haven't explained this well enough for you I'm sorry, but I'm better at showing you than teaching you. Bikeaholic will chime in when he read's this thread an maybe he can explain what I'm trying to say a little better. All I can say is , if you haven't ridin an 800 after the intake an exhaust mod's ,that when you do them to your 800 you'll wonder why you didn't do them earlier!! The high five intake from kuryakyn has been held up for distrubition because they haven't figured out the jetting for them yet , Pickpocket(ha) ordered one an he hasn't posted that he has recieved it yet so time will tell.
