I want to change my manifold, is the manifold on the 4cyl non-quattro 83' 4000 better to use then the stock manifold on my 85' 4cyl fwd 4000. Wolfsport said they don't think that the manifold on the early audi fox - vw dasher would only fit on the vw fox, as well as the TT downpipe. Any feedback would be appreciated. 1985 Audi 4000s 1.8(fwd) but still having fun!!!!
