Hi there all,

quick question: how do the Cycle Shack "M" slip-ons compare to the SE II Slip-on Mufflers?

Not interested in the sound difference, just want to know if they are comparable in performance. The reason is I am trying to fine tune my PCIII and I currently have the SE slip ons...but none of the set maps listed use the SE II mufflers so I am trying to determine which other mufflers come closest in performance?

Or are the Krome Works one closer in performance?

Thanks for any help
