twin pipe is technically the better option but it is a right pain to make.Single pipe is pretty straight forward to mod and seems to give good results over v band set up

when Jamie replaced my down pipe for the turbo elbow and 3 inch down pipe, it made a big difference about 2-300 rpm to the spool but most the difference was higher up the rev range making the car allot more free revving this made .2 secs difference over just 400m/ 1/4 mile so would most probably make a big difference on a nice long dual carriage way.

So the best option for me would be to get a v-band adaptor to fit the oe system during the GT28R install and check all is ok, then i could drive to the exhaust fabricators the following weekend fit the dano elbow and a 3" system and sell the v-band adaptor?

With regard to turbo choice to take advantage of the RS's higher ultimate flow I assume I would need WI and/or 3.8bar FPR to get enough fueling at full revs?

Dano elbow is the way to go or you could buy an Fq400 elbow and let your exhaust man join onto that.Any car will need checking out in terms of fuelling as Dan20Vt's run std regulator and no WI
