I went with B-Quiet products in my camaro. Did the same as you with raptorliner, went over with the B-Quiet ultimate matting(comparable to Dynamat Extreme but much cheaper) and then went over with B-Quiet V-comp just on the floors to keep road and exhaust noise to a minimum. I do not have carpet yet, but the difference is unbelievable with and without the V-Comp alone.
