Hi I have pro-chambers and equal length bbk headers.. but am having issues trying to figure out what kinda of mufflers I want to run.. Looking at magnaflow's.. anyways if anyone out there has any kind off equal length shorties with a mac prochamber will you please attach a sound clip and description of what mufflers your using and what you like or don't like about them. Too loud.. too quiet. It is hard to find decent sound clips with this setup and different mufflers. To many variables.
