I run the stock exhuast with a gytr insert. When I run it open with no insert, it makes it alot more snappy. But it's probrably too loud for most riding areas. Does the fmf q run just as hard as the open stocker? Do you guys recommend any other mufflers that make decent power, but aren't too loud? Also, after I rejet it for the open muffler. Will it run like a turd when I have to run the gytr?
