Just a reference of aftermarket performance vs stock on a Buell(1125), all I'm saying is do your research. If you pull up the ASB report as I suggested you will see the actual dynos. They have charts and an actual write up of each muffler.

I figured this was a little hard to see.
Where again are the dyno charts showing superiority of OEM muffler VS aftermarket?
