Just contact B&B and ask to speak to Billy himself! I was out there for Z convention and I told him about the same problem with noise for my age and he built me a new X pipe with a new set of resonators that took all of the drone at 2500 to 3500 RPM completely away!! The resonators are huge! Made a huge difference! Tell them to look up the order for Kevin Neely in CA. He will remember and it should still be on file! It still has a drone at low rpm/idle but no where nears as loud as before! I can finally hear myself talk on the freeway and I don't have to turn the stereo up to drown it out.
