So I got the Borla stingers installed this week by the dealer. For a few days I was away from my house, and I had the old mufflers in the back trunk. I noticed a vibration sound, or rattling, coming from trunk area, and I figured they were just the old mufflers rumbling around in the trunk. However, lastnight, I unloaded them from the trunk and put them in the house. This morning I was on my way to work, and I still notice the rattling from the back, sounds like the back passenger side.

I had two nuts, washers, and spacers left in a bag for me when I picked up the car.

Should I be concerned about this, does it sound like something that should just be adjusted??

 

Ya, just reposition the muffler. When I first installed my magnapaks I had a knocking noise. The muffler bracket was hitting the frame once the muffler got hot. Just bent the bracket and everything is fine now.

 

Awesome...I'll call the tech and see if I can get it repositioned. Thanks for the info.

 

Took it into the dealer, guy said a bracket was loose. They tightened it up and Wa-La....no more rattle! Sounds much better!
