Hey guys hows it going? I just picked up a brand new 08 Civic DX-G today. When I was looking at the back of the vehicle I noticed the muffler/exhaust was making a "putting"noise. Wasnt sure if it was the actual exhaust rattling or its the air coming out of the exhaust making popping noises. I'm pretty sure it's the air coming out making the noise sounds like a "putputputputputput" really fast. Do all of the new civics make noise or is the exhaust supposed to be silent? I'm new to Honda so I'd really like to know before I decide whether to take it to the dealer or not.

Thanks!

P.S. Only happens Idling
