ok, this week I am gonna make a purchase from Rocky mountain, I decided im gonna get a trail tech speedo and a head pipe for my WB slip on

For the slip on, Im just wonderin what kind of jetting changes will i need?? Do I need to rejet? If i do, can i get away with just bumpin up the main jet?? Im pretty confident about jetting, I know I can do it, just not sure what I will have to do

Thanx

With a slip on and a head pipe, I recommend rejetting. Go up 10% on the main jet and raise your needle up one notch. This is a general rule of thumb when putting a new pipe on any bike. Expect 4-7 horsepower gains with that one mod alone. Next is the airbox.

ok this is a stupid question but what the heck is a slip-on that everyone is talking about, sorry for being so thick but I just can't figure out what it is.

it is the silencer they call it a slip on because you dont get a new header with it so you just take off the old silencer and slip this one on
