Has any one tried this yet

Just a comment. I have a 09 Chev 2500HD pick-up and shortly after I bought it I had a cat back exhaust system done on it with the two chrome tips looked killer but was it LOUD . After a couple of years I wanted the tips changed from straight out the back to exiting out the sides behind the rear tires and under the ends of the rear bumper. I took it to a different shop than I had used before, the owner asked me what muffler it was and I told him it was a Flow master and he said they only use them on there race cars and would recommend a Magna flow instead and said it would be milder sound at cruising speeds on the free way so another 500 $ later it was done and he was right, at 70 mph you can just here a sweet rumble instead of the annoying drone from my previous setup . This is my experience. So good luck with your project Later Bob
