Exhaust Got Quieter?

[CodFod]

The exhaust in the Cobra got quite a bit quieter the other day when I started it up. A lot quieter in the car. Has this happened to anybody?

got cats on it?

Yes mine does the same thing but it depends on how loud my stereo is up and if my windows are rolled up or not...All joking aside No it hasnt happened but it could be clogged cats.

Your exhaust will seem quieter to you when you get in the car after a Megadeth concert.

Does it run any different?

New mufflers, or old? New mufflers will be louder until they "break in" so to speak. Also, temperature and humidity will affect how loud, or quiet your exhaust is on any given day.
