What advantages will i see with fitting one of these to my classic ej25 ,vf48,simtec,parrallel fuel rails,fpr ,swirlpot,bosch 044,japspeed decat downpipe,revoloution 3" cat back,standered headers.

Is this just a waste of money or is it a big difference from standered .

I wouldn't fit on your current setup GT Spec Up pipe,your headers are i assume Ported headers with up pipe.

GT spec headers with Up pipe is recommended only if you are going above 400bhp,and i'm not sure but on your headers you can fit GT Spec Up pipe,because its 3bolt or maybe i'm wrong,but i wouldn't brother with GT Spec up pipe,rather i would invest to Harvey Up pipe

This is GT Spec Headers with GT Spec Up pipe and here is it Harvey GT Spec Up pipe and GT Spec Headers

Up pipe



Headers




Maybe i'm wrong,but you can't put on OE Headers GT Spec Up pipe,due flange on Up pipe is different(3Bolt).

Best is ask and pm Harvey.

Yes, the GT up-pipe is a solid pipe although beautifully made. Ideally you would benefit from Haveys up-pipe which is internally contoured to speed up the gases and slip jointed.
I have an unused GT spec up-pipe going spare but as said, it is 3 bolt design.
