Round 4-1 design on Williams and square design for valver manifold.

Clio 1.8 16v has a cast item which weighs a tonne is very ugly and is a 4-2-1 design...said to be better for low down torque that the 1.8 lacks

The Clio 2.0 Williams manifold is significantly smaller tubular design and is a 4-1 design..said to be better for bhp as the 2.0 already has slot of low down grunt.

The best item IMO is a super sprint tubular 4-2-1 system available from KTR for £220? Iirc

Hope this helps

Mine must have the 1.8 manifold then :( I will get another manifold see if I notice any difference. My car made 174bhp with this manifold tho, and is really quick from low down wonder if this is helping, it is also running 172 box. I was looking to get a supersprint manifold but I heard they don't make them anymore??

Try K-Tec. They do mild and stainless ones.

genuine supersprint are bad for cracking. K-tec have similar made elsewhere, and in mild steel they will not be crack prone.

I've got a Megane F7R manifold and downpipe for sale, just needs a custom cat/decat pipe making. performed well on my car and significantly better than the williams item

I have a k-tec stainless on my Williams - no problems with cracking. Looks and sounds great too!
