Managed to get it fitted all ok. The weird thing was the previous owner had replaced the flexi august 2011 and the part had the same number gm450p but it was actually different in design to this one. The above downpipe was the perfect length with the previous one being slightly shorter. Going to drive it a few hundred miles to let the ecu adapt. Lets see how long this one lasts. Got a 2 year warranty worst case scenario.
thanks for the advice all.

. If you put it in reverse and try reversing back quickly it hits the underside of the car. You can feel the vibrations under your foot. Will be taking it back to my friend with the spanners to have a look into this.
