Not too loud at highway speed 80 and up. I had a 40 series on my 1500 that was a little loud on the highway.The 50 series is perfect for my '13 2500 HD, I had to go buy a 4 inch extension,because the main pipe coming off the cat was a little short,but otherwise this was about a 45 minute project! Best 45 minutes spent EVER! Add a cold air intake and a programmer for a permagrin.
