Well, I got tired of the silent running of the 118, so I decided to get a different rear box on it. When I was up there after he chopped the rear box off, was almost silence as it sat there.
Does the rear box do anything? It does, but not that much. I now have a straight pipe from just after the rear subframe to the twin outlets at the end. It sounds a bit better, but not by much. I guess I'll have to wait until it's bedded in and see how it goes from there. But I didn notice a whooshing sound as I got under it! But that was about it.
Anyone else tried this?
