Noticing lately after I get off the highway from driving maybe 20 miles or more, my car is a lot louder and has more resonance in the cabin from the exhaust than it does normally. I'm guessing the exhaust is heating up and the engine is actually working better but I'm not sure. Normally during the day, it's about 10 miles to work so my car barely heats up before I shut it down unless I let it warm up in the garage first. It's never as loud as when I get off the highway. Car sounds mean and pulls very well.
Anybody else experience this?
