this is what you ordered I assume? Do they get really loud at WOT? Also, how much horsepower/E.T. are you running? My motor is pretty much stock, wondering if I would see the same E.T. drop...?????I picked up two tenths switching from those mufflers to pypes race pro's. It also stopped droneing at 2500 rpms. Race pro's NOT the violators! Car isn't any louder either.
