prefferably in a beetle, and with irs, and possibly some form of kafer brace.
im playing with mine and im looking at it thinking... this wwould be a whole lot easier if i rotated the turbo approx 90deg anti clockwise to point
the exhaust out to the left rear wheel & have the intake pipe running over the top of the bellhousing...
obviously it would have to come up more, change the oil/water hoses a little and such but it makes getting an exhaust to fit alot easier since it
avoids the kafer brace, axle, irs arm etc
also if you have something other than factory stuff from the heads to the turbo id love to see it 
-bonus of the rotated turbo, makes for a smaller less bendy intake
downside is none of this idea is cheap 
Other downside is heat... Mine is actually back, down and slightly to the outside....my intake runs under the intercooler and sits on driverside next
to gearbox. The exhaust and its heat are all as far away as possible from any thing related to air intake temps.

jvls set up was similar to what your saying dave...ive got his dump and up pipes here doing nothing
^^^ could you send me pics of them fitted, not alot of room to play with in here, even better if you were coming up for warwick 
Hi
I saved these photos of Pauls exhaust.

one more,
I'm thinking about running my pipe under the diff then down down the right side of the motor and have the muffler across the back of the motor.
This is how I ran the exhaust under the diff on my old yellow bug
leave the turbo factory mount and just fit a different brace bar set up, and it makes it easier to work on.
heres an awesome example for u Dave,
of what not to do.

im thinking something like pauls could work, but with a Z section coming out from the turbo to kick up around the kafer brace then around/under
everything, its going to be fun making this quiet-ish, if only my aim was loud, that easy, 120deg bend out from the turbo to a straight pipe out the
top of the guard above/behind the wheel 
...add in a super rich
tune... fireworks
