Hi, can you guys tell me if this is normal ?
There are 2 little pipes coming out from the muffler. This morning when I started the car, I only saw exhaust coming out through one of the two pipes. Is it supposed to be like that ?
Thanks

 

yes, its a variable capacity muffler. The other side will open later in the rpm band. It keeps the car silent at low rpm, and louder and freer flowing at high

It also helps provide more low-end torque. Larger exhausts help at the high end, but they reduce low-end torque. This is a best-of-both-worlds approach.
