I heard louder but a lot less drone at highway speeds from what im reading.Let me know what you see at 75-80mph. That's where our highways typically cruise and where I heard it the loudest.
My opinion after install: If you are cruising on the highway at 65, its not very noticeable. But as soon as you hit 75, it becomes excessive (to me). I have plenty of straight piped cars and even cat less cars. Its louder than all of those (ones a V8 too). I am currently playing around with either exhaust wrap and or muffler armor to dull the sound. Hoping to cut out 50% of the drone. Which would be tolerable. The last resort will be to install a bullet resonate to try to kill the drone. Outside the truck sounds good, but inside is current a problem at highway speeds. Again, everyone has their own opinion and I am not saying the quality of the exhaust isn't bad. I was told that the AWE exhaust is actually LOUDER, which is a bit shocking.
