You would think something broke on your car all of the sudden, or ur exhaust had unbolted. I thought my car broke, put it on a lift, all was well, idk wtf causes it because I can not seem to control it coming on, but if I mash the gas it seems to go away for a few min.
This "boom" is loud and annoying and it screws with ur mind while driving, cuz its loud and unexpected. Other people in my car have asked me "wtf just happend to ur exhaust?". I sort have come to the conclusion that it originates somewhere in the engine, because JB3 fixed it, but JB4 broke it again. And a muffler is just a muffler, but the OEM obviously had a feature to hide this noise.
I've learned to deal with it, but it still annoys the hell out of me.     |
This does not address why some cars have the drone and others do not
