Cj, do you have an cabin resonance between 2-3k rpm?
My twin-chamber muffler is only annoying when the top is up. Have you driven it with the top up and the windows up and down to see if you get that nasty cabin howl that produces a dull headache?
I gotta do this to my old muffler now and see if it sounds as good as Che's. My only concern is the extra 20 lbs on the tail and the pizza oven effect back in the rear trunk.
