New at the modification process, but yesterday I installed the Magnaflow catbacks with a friend and I noticed later that night when I started up the beast there was a little rattle coming from the back right. Went away after a minute or two. Anyone else experience this? Any suggestions? Only thing I can think is to get back underneath and make sure everything is tight and not close to another metal part.

 

WEll same thing happened on my bassani. The tips werent lined up properly and the right side hanger was touching the exhaust isolated rubber hanger. Rubbing against the metal clamp that holds the rubber isolator. Just make sure everything is lined up and the hangers from the muffler dont rub against the isolator. Good luck

 

mine did the same thing...checked under and it was fine......the noise now went away and i haven't changed a thing...

 

I have the exact same problem, but on stock mufflers. I will check it myself today.
