Squeaks and rattles

[stahlight]

So I have a GTP coupe with a *custom* exhaust setup and 34000 miles. The exhaust has moderately raised the vibration environment in the car, as has the subwoofer.
The thing I would like to know from other 6er owners is this: has yours developed squeaks and rattles, particularly in the dashboard area and sounding like they're comming from the air vents while driving? I get some strange squeaking and vibration noises at 80 - 105 mph (travel speed on I-75).

Any suggestions as to the source (i.e. whats loose) or how to dampen the noises?

Sounds weird but check your seatbelt for squeeks. Thats where my hella annoying squeek was coming from (heard that from another member when I posted about some squeeks and rattles in my car as well). As w/ the dash...I dont know....havent got there yet :P (I'm trying to de-squeek and de-rattle my interior) hehe

I have all the regular noises but I have this one damn squeak and I can't figure out if it's coming from the console or the dash!!!

Do you suppose a can of spray foam would solve our problems?
Seriously though, it sounded like I had a chipmunk under the hood at 90 mph.

I would say turn off your radio, and put your windows up. Then see where your noise is coming from. I have some noise in my dash too, its mainly from the cab of the car shifting and flexing. That's whats with my car maybe that helps.

I drove a Malibu before I bought the 6, that if you drove on the freeway sounded like a zombie was under the hood trying to get out...haha....used cars these days...
