I have pypes off road x pipe, I am having a hard time fitting them still. After awhile the pipe drops and starts to leak. I think the cause of my problems is that the driver side down pipe is not bent right. I am not too sure yet though, I have to look at it some more. It droops where the down pipes and the x pipe meet. I jacked the x pipe up and tightened the bolts up as much as I could and it is still doing it. Its a headache, are other name brands like this or is pypes just a a pos.
