MPRB exhaust rattle

ASchuck · May 23, 2013

When I bought this pickup it came with a whole bunch of mods including a very nice MPRB exhaust system. for some reason there has been a slight rattle around the muffler and I've tightened all U bolts and everything around it. Could the rattling be inside the muffler? It just sounds like something is loose but I made sure nothing was loose before posting. If anyone knows please feel free to post.

Is it rubbing and bouncing against the frame?

Wondering if it is also bouncing against the frame, possible broken baffle?

ball up your fist and punch the muffler!

But in all seriousness, if you smack the muffler on the side (not knuckle punch it) does it rattle? I've had to use the 'rattle' method to find something was loose in my muffler before.

I agree with WhiteExpress. I have a Mbrp exhaust too and when I coast around town and the rpms are low I get a rattle too but I'm almost 100 percent positive its my heat shield, it also happens when my mds kicks in.
