You'll find it hard to get any 4-1 manifold which doesn't hang lower than a 4-2-1 manifold. The 98spec ITR OEM 4-1 manifold has proven itself well even against some big name aftermarket manifolds.
Yeah u have a good point there, I guess the 4-1 is a bit big so it has to hit the gound, have u ever had any ITR 4-1 Manifolds?? Wat did u think of them? Any hits with it?
i was running a mugen 4-1 mani that has a scratch plate on bottom and that i know of this was fine for clearence, mine was pretty low, i will have a look at it when i take it off in next week or so to see what it like
i got very good power from my BC one, and it was on my dc2 which is fairly low and it wasnt hittin the ground. have a look at my thread i recently posted... took it off for the nct and i can really tell that its not half as torquey... think its a Y shaped 4-2-1 though.
