Who is happy with their Q4? I just put mine on last night. I haven't fired it up yet. The high temp gasket needed to dry first. I'm a bit skeptical on the noise to be honest. I have been running the stock pipe with the pea shooter silencer removed. I really liked how quiet it was with the pea shooter but we all know how cruddy they run with them in. After I put it on I thought maybe I should have gotten more of a turn down silencer:excuseme: Any thoughts?
