Honestly, when I drive I always shift at 2 rpm and try and drive under 2 rpm. When I do, I can't even really hear my exhaust at all. You can really control it, but when you drive on the highway then yeah there is a bit drone but with music on you can't even tell.
What I like about the exhaust is just the fact that I can control how loud I want it, and it really screams just at 3 rpm, but at 2 it's not even noticeable in the car. But to each his own I suppose, I love the exhaust for the price.
In my opinion all v8's need a roaring sound, and that's what my muffler shop created!
