G40 Centre Section on my GT...

[MartinB]

Hi all, I think i posted this on CP but got little response...

I currently have a 4 branch/decat downpipe mated to my standard GT centre section with a G40 backbox.

Will i notice any gains with a G40 centre pipe or is the GT centre not that restrictive? 

The Manifold is a TA Technix one, from PhilJ not sure of the bore TBH, will the G40 centre pipe go straight on or will i need a reducer?

sorry for all the questions but I thought i'd ask some people in the know!

some benefit but probably not worth getting dirty for in my eyes

will go straight on, might as well if you have a G40 back box. Although non-genuine items seem to be more restrictive.
