My moms 07 exhaust sounds like it is fluttering at idle and there happens to be a lot of smoke coming out of them as well. the tone sounds deeper than my 05 as well. Is there something different with the 6.5 gen stock exhaust and 6 gen exhaust?

Here a sound clip i just recorded tonight. this is after 30 mins of driving and it sounded like this before as well. just want you guys input. thanks in advance.

does sound a llittle odd. take it in and have it checked. any dash lights on?

 

im going to do that but wont be able to until friday because i got school during the day. i wonder if any of the other 6.5 gen owners have had any issues similar to this. no lights are on in the dash and the car still drives fine. i just thought it was an unusual sound.

 

Def not normal. Hopefully it's just a leak and a gasket replacement will fix it.
