Sorry to unearth this but I am wondering if anyone knows of anyone running a free flowing exhaust manifold yet or if anyone is producing a good one yet?
I am considering going to stage 2 so i'll be fitting a turbo-back system, naturally. However, after that at some point I think I might consider Hybrid K04 but it seems quite pointless unless I can upgrade the exhaust manifold. I believe it poses a rather large restriction and limits the hybrid turbo's potential, with very few Hybrid LCR's making the 300 - 320bhp estimates. I stand corrected if I am wrong though but there seems to be little difference in figures between Stage 2, FMIC & TB vs Stage 2, FMIC, TB & Hybrid...Is it the manifold that's holding things back or are there other issues?
