fixed exhaust drone and rattle
i had developed a horrible drone, that you could hear and feel thru the entire car, in 2nd thru 4th gear around 2800 to 3000 rpm and also noticed, at idle, what sounded like heat shield rattle. got under the car and looked around for possible loose heat shield and found nothing. i started pushing on the mufflers and exhaust and noticed the right side bolt in pic was loose. so i tightened it not thinking it would fix anything but man was i surprised. after tightening that one bolt both issues are GONE! no drone and no more rattle at idle. just passing on in hopes it may help others.
