I was wondering if anybody here runs the FMF Q2 exhaust with the powerbomb header? I currently have a White Bros R4 exhaust on my YZ426 but it is way too loud. I am just wondering if I will feel any performance loss with the Q2 and powerbomb combo. Anybody have any experience with this setup? I just don't want to be kicked out of any OHV parks or get a ticket for a noisy bike.
