Will Stock GPX headers and down pipe fit a GR?

[onnzo]

Hi guys,
I just got a FTO GR 2l non mivec with custom extractors and down pipe. It is too loud though so I want to return the headers and down pipe to stock.

I cant find any stock GR headers / down pipe but have found some stock GPX headers / down pipe.

Does anyone know if they are interchangeable? I know the gpx piping is a bit bigger but will it still bolt up to the head?

From browsing the forums, apparently the RPW GPX and GR extractors fit both models (but the mounting flange at the down pipe is a bit different) so im thinking the stockies are similar and will bolt in.

Does anyone know?

Thanks,
Mike

AFAIK, you should be able to bolt the extractors on, not so sure about the downpipes though, you may have to find out the hard way!

Thanks for the tip,
I contacted two FTO specialists (kempy's in NZ and RPW in oz) they are also of the opinion that it should bolt right up - the only problem will be the flange that bolts up to the cat - it is a bit narrower on the GR as teh GPX piping is slightly bigger - I should be able to just slot the flange to suit.

I will find out this weekend and post my results. Hopefully they are positive!
