My PE went quieter
Lately my bmw performance exhaust has benn sounding great. Just the right throatyness, and great at high end. Got it late summer and super happy.
Sunday driving along highway in 6th under 2500 rpm the exhaust all of a sudden went quieter just like when your ears pop. It seems to gone back to the noise level before it broke in, maybe quieter? Any thoughts. Have any others have had that happen?

Is your air filter clean?

If that really happened, it would be the airflow now being limited because of a foreign object or the temperature going drastically higher. Since OP was driving when it happened, I would opt for the 1st option.
Mine also gets louder under cold temp Pulls a lot harder too!

i dont think its the filter but will check once we get a warm day.
as far as something plugging intake--possible but there was no crap flying around that day. i have noticed too that the cooler weather it is a little louder so it seems, could be because of the sounds waves are different in cold weather. But it was cold that day when it happened. I am wondering if a baffle has shook loose or something else inside muffler?
