Lately I have obtained a popping/metal noise when I take off. It does not do it all the time . I crawled under it today and all u joints seem to be ok. I did notice the tail pipe has been banging against the rear shackle bolt. I banged it on there and the noise sounded very similar . The very last. Bolt on tail pipe hanger has apparently fell out so I zip tied it by up just to see if any difference. I did notice it I'd not do it as much. Any one have any tips. Going to put a bolt back in to see if I can tighten it up some more

 

If putting a new bolt in it doesn't fix it, grab a new hangar and get it on there. An exhaust that is flopping around is not a good thing and you should want to drive around with it like that for long.

 

Put a bolt back in last hanger. Got er tight. Took her out for a test run. Quiet as a mouse. Glad it was nothing major
