I have a 2001 RM125. It has a Pro Circuit pipe and shorty silencer (came on bike when bought). I want to get a FMF Q silencer to quite the bike since I trail ride not mx. Actually either way quite is better for me. So the question is do I have to buy a FMF head pipe also or will the FMF Q silencer mount up with the existing Pro Circuit head pipe?
Thanks
