I just thought I'd throw in my with some feedback/experience with the new Dynomax VT's. I was running a superstock setup with max wedge/superstock exhaust manifolds full 3" out the back X pipe and TTI tailpipes and had a terrible drone with flowmaster super 40 series (flowjunkers). I read all the forums about exhaust/drone and what I gathered was... I'd never be able to rid the drone with cast iron manifolds. Well... I can't say enough about these mufflers! The VT's took care of it all! No more drone/vibration, I can hold a conversation and listen to the radio! My girlfriend will ride with me in the car now, so that says a lot!

Anyway, to say the least I'm very satisfied! My father is running a 528" Hemi and has just ordered himself a pair as well.
