6-2-1 manifolds these best on a budget?

[Ciaran 4]

considering buying a VR very shortly and planning to spend about £1500 on mods.

being suspension induction and exhaust. just want to know if i buy a manifold which works most effectivly performance wise and is not £600 like the super sprint 1? and also i wish to keep the cat on the car as the hassle of de-catting and re-catting for mot's is to much hassle!

Try flowing and port matching the existing exhaust manifold first as that can yield quite good results and is cheap to do. Proper tuned length headers (to counter act the unequal length ports in the head) would probably see better gains, but finding one that's known to work well, other than the 'work of art' SuperSprint could prove tricky.

well looks like it would have to be a supersprint then what sort of gains would i expect?

You should get a noticable gain in the midrange if the runners have been tuned right. Not sure how much of a gain you'll get in numbers though. Very few people in this country use that manifold, in fact I don't know of 1 person, so you may have to find out for yourself!
