P.S. Do u think exhaust wrap would add some insulation and quiet it down?
Live in FL so windows are never down in this heat maybe sunroof open on a cool night about it for me.

It's normal, I had literal hissing on decel, like someone whistling, and I just had a clamp too far back. Once I fixed that the issue went away.

If you're worried about leaks, JB weld is a rather permanent fix
What do u mean clamp too far back?

One of my exhaust clamps at the collector wasn't all the way forward on the front of the off-road pipe, it was back allowing for some exhaust to escape, but like I said it would literally whistle on decel.
