Quick Exhaust Question

Bike is jetted for Yosh low mount RS3 slipons, would a change to Leo Vince high mounts require a re-jet?...

Not likely...the change from stock to yosh by itself didn't require a jetting change.

Really? I thought that rejetting must be done if ANY type of aftermarket exhaust is put on...

Also, to add to this question (hope you don't mind Oahu), but I have standard mount pipes on, is it possible to order the high mount pipes, or would you guys fabricate high mount pipes?

The SH is more sensitive to intake mods than exhaust mods. You can put aftermarket exhaust an still run stock jets, but if you put in a K&N filter, you must rejet to get it to run right.

It is recommended you rejet for any mod, but not needed for exhaust.

hmm... When I bought my bike it already had a K&N installed.. though it doesnt make enough HP (i had it dynoed) for me to think it has a jet kit... This may be something for me to look into....
