Yes we fabricated the collector and downpipes on my GTV we used a 3inche pipe running straight out the back.
On the others we still used the OE exhaust from just after the cat.
That turbo will work although it is a bit on the small side but it will start boosting from +/- 2000rpm and should be fine up to the 7000limit with a bit of boost drop which is actually a good thing in certain circumstances.
We will do costing on the collector and downpipe to merge onto the oe pipe just after the cat.
