I've got a rattle as the car is warming up...noticeable at idle, but if the exhaust is still cold and I press the gas, I'll get a heat shield sounding rattle around 1500 rpm's.
What's different is that the sound is coming from the rear and possibly the muffler.
Can anyone tell me if there are heat shields around the muffler area or at the back end of the exhaust? Or is it something internal inside the muffler?
I haven't had time to crawl under the car to look, but I am also not allowed to work on a car in my apartment parking lot unfortunately
