I have a 2004 E55 with the Kleeman stage two package. The exhaust is stock other than the long tube headers. I want more sound out of the car but don't want to go too loud. I would appreciate any advise or ideas on the best way to go about this. I was told by somebody that they saw where someone on here hollowed out the stock mufflers to get more sound and retain the stock tips. If anyone has any suggestions or can direct to someone that can help I would sure appreciate it.. THANKS
