    Red face Detached Muffler Survey-------------

    Hey Folks,

    Eight Months ago I installed the Magnaflow Exaust system on my vehicle. All hooks and bolts were tighten really well. At any rate, on the way home from work yesterday..... the "overaxle pipe" that is attached to the muffler came loose, causing loud twangs at low acceleration. I ramped the mother up and reattached without a problem.



    Has the detached ever happen to your exaust through time?

    It was obviously not clamped tight enough.

    I clamped it with extra torque when installing. I'm thinking through time and vibration it came apart.

    what type of clamps? Band clamps or u-bolts? Band clamps will stretch over time but if you tightened u-bolts down it should've move, a u-bolt will actually crush the pipe a little bit and it's a real bear to get apart or back together for that matter. If they're u-bolts just make sure you crank it down real good.

    They are U-bolts....... I crushed it down good yesterday as I reattached. Magnaflows kits comes with different U-bolts..... to my surprised when I did both of my vehicles, the more expensive kit came with U Clamps that are more diffucult to tighten than that of the cheaper set.

    U-clamps are permanent. The best way to secure your exhaust but also the ugliest! It also depends on where the clamp was installed.

    Band clamps are not permanent. They require alot of clamping force, but once again, the clamp must be positioned correct.
