I'm ordering a slip-on this week along with the comp ecu. I was wondering which pipe will be the loudest? FMF, Two Bros, Yosh, Dr. D? Also, does removing the snorkel in the air intake actually provide more power? Or is this just something some guys are doing because they "think" it adds more power? I know the exhaust question is beaten to death, just trying to find the appropraite info on the new wr. Thanks for any input guys!
