This is what I've found, but around 50-55 is more comfortable..

Also on the exhaust rumble thing, my old catback had an awesome deceleration crackle/burble. Since getting my extractors/cat/mandrel 2.5" I thought at first that it didnt burble on decel, but I've realised it does, its just much deeper and softer. Its harder to hear, but sounds a whole heap meatier.

So when going down a slope I do occasionally open the window, drop down a gear, and listen to the deep thumping burble. Its nice, gotta get a bit of enjoyment out of the car ;)
