if you are willing to shell out the bucks, you can get custom piping on your Maxima, and run dual exhaust on your 03 with the G's mufflers, see if you can purchase the mufflers from a wrecking yard(they are a kick to the wallet new). OH, and look into a new rear bumper that supports dual exhaust for a 03 Maxima, if you don't it'll look dumb from the rear.johnnyd6404 wrote:I've got the Megan catback and at idle it kind of sounds like the FX same tone but while driving its much louder. You may be able to use the G's mufflers with some custom piping to get close to that sound... maybe?
