I think GPF back is basically an axle back, but with extra tubing to delete the resonator but preserves the GPF/OPF.
I have had no luck yet with the valvetronic midpipe. Valvetronic said they have never come across the issue i am having. I took the midpipe to a very famous exhaust fabricator near London and also to PCW and the advice was that the part of midpipe that connects to rigid downpipe is not angled properly and will need some modification.
There is also another issue, the gpf/opf sensor hoses are not long enough to reach the single midpipe due to their location. So I will need to modify that bit as well. Not as smooth sailing as i expected.
