Had my exhaust unplugged all week. Still sounds good. Cold starts are a bit louder, but still acceptable for neighborhoods. Idle stutter when stopped and in drive is significantly less. The plugs are easy to reach. They are right on top of the muffler. All you need to do is slide the white clip out, then press down on the clip and slide them off. I would suggest covering the loose plug end with electrical tape or a balloon to keep moisture and dirt out! They don’t hang down enough to contact the exhaust, so heat doesn’t appear to become an issue. VERY HAPPY not to hear the exhaust rattle every time I start the truck! Even happier that it sounds a little more aggressive at startup and idle!
