Thank you for that first hand info, Mike. I think that probably eliminates any thoughts of an affordable two-out that won't be too loud or drone.
But I could possibly still fab a single-out with a Magnaflow. I do like how those mufflers sound. Too bad this one (#14210) only comes in full polish, that makes it more expensive than it needs to be. Other than the price, it should make for a good option.
