What's really strange is that sometimes the exhaust sound is very civil and not even that loud even in the same rev range. For example, on the way to lunch the exhaust sounds really nice and smooth. I'm even able to listen to music while accelerating. On the way back, it gets very loud and sometimes raspy. My coworkers wonder about the same thing. I'm not sure why or how that happens.

EGT heat must be effecting it?
My exhaust on my tC in the morning is nice and loud, from the cold start. But later in the day after its warmed up, its back to the smooth purr.
