Usually to get rid of drone, you replace the flowmasters with magnaflow.
These are super 44's by the way, I am very nervous about droning. I hope it's not an issue. I wanted a magnaflow exhaust for this one but what I found available was this flowmaster kit.
to 99, it's a crossover tube.
Hoping that will tame the drone.
Thank gawd you are putting a crossover tube in it. It should help the torque a little, but it gets rid of that Cox airplane sound effect that sound horrible to me.
