Thinking about taking the spark arrestor off of my 08 Wolverine. Has anyone done this yet? If so did you really notice any performance increase or just sound. Also from what I have researched you do not have to rejet it was this the case when you took yours off?

 

I cut mine off, and drilled out my can, then reinstalled the tip after polishing it. You can hear it here. It's a 350. Mine has had the port polished a bit too.
