So I had a muffler shop install a set of pypes axle back "pype bombs" on my 12 v6. After about a week I had some rattle under acceleration and when the shop looked again they said one of the clamps had come loose and was rattling off a hanger. Unfortunately after they "fixed it" it took all of 3 days for this to start up again.
Has anybody had problems with the clamps? If so how did you fix it? And does anyone have any other suggestions on how to keep the rattle out?
