I've been using cutouts on my car for years.. Right now, I have no mufflers on my stang.. just pipes where the muffler use to be.. I was wanting something louder so I was looking into getting some cutouts.. I don't think the car is that loud now.. Try driving around with a cutout in the intermediate pipe of an f-body.. That is loud... Could you possibly post a sound clip of the cutout wide open? I would appreciate it.. Thanks..
