Thread: 6 Branch stainless manifolds

  1. #11
    Corrado blowing like a tractor as of yesterday. Garage checked for me this morning and the 6 branch has split just forward of the connecting flange. Seems I have a choice between a new 6 branch or reverting to an original manifold but not sure whether the original downpipe uses a compatible fitting to cat pipe . Quite a few new 6 branch on ebay but all advertised for Golf 2.8 VR6, the Corrado is not listed among the compatible vehicles, and any that say for 2.9 VR6 are more expensive than I can justify. I would be interested to know if the 2.8 will fit.

    Surely you can get your money refunded? The OEM manifold will fit to the original cat pipe no problem unless anything's been changed there - what was wrong with the stock mani?

    TBH, these aftermarket 6-branch ones result in only marginal improvements without a lot of other engine work and most of the differences tend to be negative. The factory system was built to a pretty high spec and is well matched to the engine, and you need to be very careful about an aftermarket down-pipe/manifold generating additional heat in what is already a pretty hot engine bay.

    Horrible things those headers IMO, just took one off my Golf MK2, it was brand new, the last owner fitted it, had to fork out £300 for a new OE Manii KR 16v from Classics in Germany. I would try and source a VR OE Mani second hand unit with the down pipe personally.

    Ported and polished my OE manifolds, tig'd up the downpipe flange externally and gound and polished that as well. Not keen on ebay manifolds... you're going to be buying twice.

    I'd agree there - claims of 10-20%, so that might be 210 horses bolting straight out of the stable with one of these on - you'd have to laugh - even the best modified naturally aspirated VRs with several thousands spent on them struggle to make 210-220. But you have to love a dreamer.

    My problem is the bloody drone they make. all most gives me headache , pretty much changes the whole character of the engine to the point where you couldn't even feel or listen if the engine is running smoothly, also as mentioned the potential heat damage to the engine bay and cabling.

    You could get the split welded up. That should be cheaper than replacing it.
