So the purpose of my post today is to throw out a small PSA to those of you that are currently dealing with or may at some point come across an issue that I have experienced recently.
My story begins with me installing my AWE DP, pairing it with my track catback that I have had on for about 6 months or so. I knew the volume level and drone would increase but I wasn't too concerned as I don't DD my car. For the first 100 miles or so, all is well. Foot on the loud petal, car screams, pure engine and exhaust noise, couldn't be happier.
But at a certain point, a buzzing sound from the rear end of the car develops at around 2.1k - 2.4k rpm's. It happens upon acceleration through that range, a quick blip of buzzing during upshifts, and is less audible but still present @ WOT around 4.5k.
So I start my investigation in the back of the car, tapping and flicking anything that i think might be the culprit. I remove my license plate frame and tighten the two screws on the license plate. Still there. I remove all of the trim panels on the hatch and take it for a drive. Still there. I check the spare tire compartment for anything loose and remove any tools/spare parts that I have stored inside. Still there. I remove the rear deck lid and drop the rear seats down. Still.There.
I finally decide to jack the car up and take a look underneath, even though I swear the noise is coming from higher up in the car (like in the rear hatch). At this point I am hoping it is not the fuel line issue, as I would need to take it into the dealer and would most likely remove my DP & Jb4 which I was not really prepared to do. However, the first piece that I tap on is the suitcase muffler heat shield.
5 minutes later....
Took it out for a drive and there is no more buzzing! With the track exhaust installed there is really not a lot of direct heat being blasted onto the area that the heat shield covered, so I don't foresee any issues with it not being there.
So when in doubt, rip that bitch out.
Anyone else have/had any similar issues after installing a louder exhaust? If so, mind sharing what your buzz or rattle was/is and how you went about resolving it? I searched around before tackling the issue but didn't find much concerning a buzz or any noises in the rear of the car due to increased exhaust noise, so maybe we can collect some common issues and solutions to help those out who may be experiencing this issue or may come across it in the future.
Cheers!
