The video I linked to in post #11 is the Pypes transverse with the racepro designed muffler. I put that system on a couple years ago.
Actually just put another one on another 2nd gen that I restored just a few months ago here..... They have a nice bark to them outside the car, but inside the car they are pretty darn quiet, and no drone.
