I had that on my old civic this, i have one on my wrx. although the valve got annoying at idle and deceleration since im unequal length headers and what not, so i welded it to stay open. but cruising and stuff like that it was dead quiet. ---

Stock muffler off something else, that fits under there. Even if its only 2.25 or 2.5", reducing it back there isnt going to hurt performance to the point that its detrimental to the car, and it will be silent. Then put a QTP infront of the rear suspension, Y’d and dumped right there. WOT ricer fly by’s cut out open, flip the switch and nobody knows what happened.
