Has anyone got a exhaust diagram? help
« on: 12 July 2012, 18:43 »
ok my new manifold and decat pipe holes don't line up.

manifold flange hole centers are 74mm
decat flange hole centers are 82.5/83mm

the holes on the manifold are big so I  could drill out the decat but not the point.

I would like to know if all mk3 gti  8v's have the same manifold?
I know the cats are different length but don't know why?

I have a short cat on my gti but bought a early gti long decat, I  did this so I can cut a section out and weld in a flexi pipe. I don't want to do this now if the hole pcd is different on the cats.

anyone got a genuine cat lying about to measure the hole gap?

any help is much appreciated  :smiley:

My last ADY had the 3 large centre holes and my AGG has 3 smaller pitch, the ADY did have massive CAT on it though :undecided:
Suggest you look up on ETKA and examine the exploded diagrams.
You are talking about the down pipe flange to CAT flange?

yes.

I have bought aftermarket. That makes sense. Manifold must be same as agg and the decat is ady. So I could get a short decat and the holes would match the manifold.

I'll check now
