I also run a stubby for the same reasons, and it also works well for me.
However, to answer your question......cbrgaz nailed it.....you can get a short bend running through about 30 degrees on ebay for less than a tenner.....either slip on or weld on, and you can make a 'weld on' one fit by cutting a slot with an angle grinder then binding it with an exhaust clamp pretty easily.
As an alternative, you can get assorted lengths of flexible connector pipes, so you can adjust to ANY angle of dangle, but they look rather different to a solid wall pipe.
All you need is the OD of the section you need......offhand, I think it's 54mmbut check that
Don't forget to stick a rubber connection into your setup somewhere or you could end up with some nasty vibrations and/or rattling at certain engine speeds......a simple bolt through mushroom is enough, and they are pennies from any online 'zorst place.
Wudo used to make a lowering kit for the lebbenfiddy, but it was stupid money for what amounted to no more than a couple of ally plates and a 4 inch(ish) bend section....about 80 quid years ago
