It will definitely cause a difference in performance, as its causing a lack in back pressure.
Prob find it causes the car to use slightly more fuel in some cases too.

Do you know where its blowing from?

thanks,

yeah from the bottom of the first pipe the cylinder closest to the ecu
I need to make the holes on the manifold bigger so it go onto the block with the studs in first.
And need to fit a new gasket
