Now that the cold weather is here. I have noticed that my car sounds way louder and more rough when its cold. Not running rough, just the sound is more mean. It takes it a good 5-10 minutes of driving before it gets fully warmed up now, and sounds normal again. I have a completely stock exhaust accept magnaflow muffler deletes. This just started last week since it got cold out, and now I notice it every day. Anyone else notice this? Once the car warms up, its normal again. And it runs great with no check engine lights.
