I am toying with some mods to the stock setup. I am having a hard time paying $650 for the AWE NRDP just for noise increase. If all they are doing is eliminating the perforated/chambered resonators then I may have my local exhaust guy cut those parts out and well in some SS pipe in the place.

I will probably end up going with the AWE catback next year since AWE claims a 10-15 hp increase at the wheels.

Since if you unplug the rear exhaust servos it trips a code in the ECM, has anyone tried to take the servo apart and just keep it from actually manipulating the diverter valve?
