Aftermarket exhaust? Rejetting or jet kit required?
Hi guys I am new to the forums here. I have a 2001 Vulcan 750 and I just recently purchased a set of MAC pipes off of Dennis Kirks website. My question is, after putting these on will it require a re-jet or will i need a Jet kit that can support the exhaust? Im a newbie here so I hope I am posting in the right place. Any feedback would be appreciated.

Shouldn't need to, especially since you're losing the scavenging effect of the "power chamber" crossover. The main restriction is the intake to the filter pods ('ears'). Use new gaskets. If you do rejet, check out my spreadsheet in the stickies. Don't go too big or you'll just muck things up.
