They do make noise and can seem loud but when I was told by other people that they were quiet compared to their adjustable ones, I relaxed. I was extremely worried about it. I check everything I could, 0 lash torque down, checked where they sat on the v/s, got new pushrods and everything turned out fine.
yeah Jason , I was worried as you...until someone stopped by who had purchased the same kit and while I was installing them he told me he hated them because they were loud........once you put the exhaust on you wont hear them lol
