2010 Grabber Blue Shelby Posted April 19, 2011 Report Share Posted April 19, 2011 Guys, I have American Racing headers and hi-flow catted X-pipe with MAC "MMS" Mufflers. The car is way too loud and drones at highway driving. I need to quiet it down a bunch of notches and was thinking of welding in resonators after the x-pipe. Has anyone done this? And if so, what brand and size did you use? I was looking at these from Vibrant performance.
