Vx Calais Pacemaker header question??

[Coop450]

Hi Guys,

I have picked up a set of pacemaker headers 1 - 7/8, 4 into 1's
My question is , will these bolt straight up to my vx Calais or is there some mods needed?? The headers
were off a vx ss.

Any info appreciated.

Cheers Coop.

they will bolt straight up but the 1 7/8 has 3.5 inch flanges i believe unless you have 3.5 inch inlet for the cats they will have to be modified

Thanks bud, cats are not an issue I got 2 cats with the headers that suit.

I have heard there can be trouble with 4-1s not clearing the calais' variable assistance solenoid on the rack.
No idea how much truth is in that though.

My HM 4-1's clear the variable rack easily, can't speak for pacey's though, although can't see why they would be different.

I had no trouble with mine & yes they are pacemaker
