Car oil temp goes above 100*c (212f) and I start noticing some lag/timing pull and more pronounced at 110*c (230f) which is cool since that's normal but the real question is this:

Is it normal for your exhaust to sound louder as it gets hotter? Especially in the 1.5-2.5k range? I found that it was deeper/louder than normal as if the car was warming up.
