Glad to hear your happy with your ninja system i am thinking about changing the back box on mine for a ninja, how loud is it??

...i have the Ninja backbox. Looks good and sounds good. Burbles on tick over, rumbles nicely while driving.Turns many heads and sounds like a Scooby should. Had an open neck H&S downpipe fitted and the whole exhaust system sounds even better and a bit louder.
Not loud on motorway driving.
I reckon it sounds quite similar to a Scoobysport system...but looks better if you like the big 5" tail.

For the money you cant go wrong, it looks alot more expensive than it is.
