mk1 golf 16 exhaust manifold..
It would be hard to tell the specific power gains on a Mk1 because you can't do a comparison test with the original manifold (because it doesn't fit). Also you have to bear in mind, you've also removed the cat (probably) and I'll be running a different cam and other mods which should gain me a bit more power.

4-2-1 vs 4-1
But none of this happens properly unless the manifold is fully tunned to your engine. The lenght and diameter of the primary and secondary branches are decided by your choice of camshaft, capacity, and where in the rev range you want the manifold to be most efficent.
The last manifold I made was for a 4.2 v8 and had 36 inch long primarys and these were shorter than needed as finding space for 24 foot of inch and 5/8 pipe is hard work.

Damn good price as well, with the current exchange rate its around ?180 (plus obviously very expensive postage…)

but other than that…
Finally a 4 branch thread that has actually been useful!!
ive spent so so so many hours over the last week looking on the net for info about manifolds and this is the best thread around.
It looks like i will be going for the storm one asap.
i hear and have seen lots of pics of he ashely being cheap and not fitting any car, other than one.
Will let you know if/when i get it and how well it fits on mine also.
thanks again everyone.
oh also, does this manifold fit the 9a engine? or is it for the kr? or are they the same?
