Silver Rocket

I have a 07 Z06 with about 27,000 miles on it. Lately, I have been getting a loud humming sound and it sounds like it is coming from the dash area. this sound starts to happen when I get over 70 mph. I also thought it might be the roof starting to delaminate. I put a piece of tape along the leading edge seam to prevent air from hitting the seam and getting under the roof lip, but the humming sound is still there. This sound does not always happen, it seams to be random. Any thoughts out there???

Check your cabin air filter. I had a leaf in mine that would buzz at highway speeds. Drove me crazy for 6 months.
