Hello forum, long lime listener first time caller here. I have a 2010 Mustang Shelby gt 500 close to being SuperSnaked but with other parts and done here locally not sent to Vegas. I have a Magnoflow muffler on my stang, noticing lately that when i gear down and the muffler has a bit of back pressure that I hear a tinny sound... especially while turning left because I believe the sound is coming for the drivers side rear. I think the muffler is rattling against the stabilizer bar cross the bottom underneath. There is an alimumium pipe or hose along with a rubber hose that look like they could rattle if the muffler had some pressure on it. I was thinking of clamping the two together and put a heat resistant foam block to prevent it from happening but I am not exactly sure. I am by no means a gear head.

I apologize if this is posted in the wrong area or if this has been discussed before. I hear a sound like someone has dropped a sheet of tin behind the car sometimes.... very weird. But my motor and muffler sound so beautiful that it is hard to hear for the most part.

I blew a spark a while back and some block smoke came out of the muffler and I am not sure if something is blown inside etc.


I am getting a P0104 error code also which is a MAF error but that is another story.

Good luck to all and thank you in advance
