Exhaust hanger bushings are now stuffed with small pieces of towel. Lets see if thats where this rattle is coming from
Just installed my magnapack 2.5 inch cat back with no problems. It was the easiest install i have ever done and no rattles. I dont know how you guys are all getting a rattle but mine sounds great. If you have the 3 inch cat back its possible that the tubing is rubbing on something from the extra width but the 2.5 inch is working great for me and no problems with the hangers. Are you all in 2010 mustangs because i did have an issue with my magnapacks in my 97GT? It was rubbing on what looked like a bracket near the driveshaft. I just ripped it out and the rattle went away. But in my 2010 it fits perfect.
Gotta love the 'packs!! Where in MD are you, I'd like to hear them on a 3v?
TIm,
I installed 16571 from Magnaflow, did you install the same? 16574 has a different size muffler and is still a magnapack. I had no rattles for a few days. Additionally, the rattle is not all the time. You may experience them, you may not.
I have checked everything in the trunk and everything under the car to make sure nothing is loose. Since I have stuffed the exhaust hanger with material, we have not experienced any rattles. This could mean that it is, indeed, the exhaust hanger bushing, like someone else mentioned, or, now, the system does not move as much and nothing vibrates. I hate to ghetto rig something, but it seems like the only fix without having to spend a chunk of money.
