vts mk1 manifold: 4-2-1 or 4-1?

[lowlandsblackest]

Could someone tell me what's best?
a 4 in 2 in 1 manifold or a 4 in 1?

I've allready got a de-cat pipe and a 2in. full stainless steel exhaust without mid-silencer

I'm thinking of chipping/camming in the future too
So, what brands/prices/options are there, and what's best for me?

I'm more interested in accelleration gains then in top-speed (or maybe both if possible?)

Thanks allready

i have a 4-1 on my vts , and impressed with the gains i got, my mate went for a 4-2-1 on his vts and noticed little gain bottom end, and he now wants a 4-1, i think the 4-1 gives better mid range and 4-2-1 low end, hope this helps abit smileys/smiley2.gif

i thougth it was 4-2-1 which gives power in high range, i might be wrong.

muly do u have a pic of your manifold?

[muly]

according to GMC motorsport a well manufactured 4-2-1 give a better bottom end & the 4-1 give better mid range-topend

they only make 4-1's due to the limited space GMC Motorsport (http://www.gmcmotorsport.co.uk)
