I was gifted a Poison Spyder BFH II rear bumper a while back, and I'm having an issue with the bumper sitting and rattling on my exhaust.
It barley touches it, but it's enough that the ending will cause noise.

I am not sure if anyone has had this experience with a Poison Spyder bumper, but figured I'd ask...
The bumper has been a pain... I had to cut off the whole rear frame cross member just to fit it, and even then the bolts holding it up don't seem to help.

Trying to figure out a way to stop the rattle without having to replace my stock exhaust with something else...  Dunno?

Is it just the tail pipe or the muffler it self? You can adjust it for clearance, there are several ways to do this, depending on what part is hitting. Pic?

Here is a picture, this is what the bumper is sitting on. It sometimes won't rattle on it, but then it does other times.


Closer look over here, there is that one end that seems to be touching more than others.

I would try to adjust the muffler mounting points first, but beware that this may put stress on the forward pipe.

If it was mine I would pull the muffler, take a grinding wheel and remove just enough material to clear the muffler, paint bare metal, re-install muffler.

Seems like the perfect excuse for an aftermarket high clearance exhaust.

I was thinking about this as one of my options, might be the only way to fix it without actually spending money on a new exhaust system.

Thank you all for the input  Cheers

 disconnect the muffler from th3 pipe feeding it. shorten the pipe feeding it by 2 inches and reassemble.  I am sure you know a shop that is capable.

That's too much like work. If you have remove the muffler, your better off modifying it, you can cut the input back 3/4" and bend those mounts forward, when re installing the input. However, you may not even have to cut the intermediate pipe, since it's a slip fit loosing it may allow it to slide farther into the muffler and give you the clearance.
