My wife gifted Eljay with a set of Cobra 2 into 1 Pro Pipes for Christmas, which I installed with the greatest of ease (cough...cough). I realy like the sound, but boy they sure are loud. So my question is this.: Who out there has installed a set of these on their 900 and then did something to turn down the volume a bit and how did it work out for you? The two best options I've come across is either a baffle insert or add some fiberglass wrap around the baffle on the inside. The only baffle insert I could find for the Pro was the Hard Core from Smartpartz. Any suggestions would be greatly appreciated... Thanks!!!
