I just got my 99 FRC about 2 months ago,any time I let off the throttle I hear this weird clunking noise out the back of the car I cannot figure it out any help of what to look for?

Mufflers hitting, bad trans mount,bad balljoints, play in the rear end, worn driveshaft couplers. Thats just a few. Good luck.

Could it be the seat rocking? When my bf first got his Z06 I noticed a clunk too and I thought something was wrong...turns out his seat was like a lot of other corvette seats, where the seat track gets loose or something, and it makes this funny clunk noise...

I know its not the seat sounds like it is drivetrain somewhere

the clunking noise is normal, it's a gm thing

Look at the muffler hangers, make sure they arent bent, may cause vibration sound.

I did take a good look at the exhaust system nothing is bent or loose. car is not getting any vibration which would leave be to believe it to be the trans mount.
