I am not sure what six bolts you mean. Heres a pic of a throttlebody and manifold already removed if that helps.

these 6 bolts are for holding the downpipe to the cat.

The throttle body is bolted to the side of the inlet manifold by 4 hex bolts.

remove the throttle cable, unplug the wire harness on the back corner then remove the bolts.

there's two vac hoses which connect to the bottom of the throttle body. I left these plugged in and just moved the throttle body to the left hand side of the engine bay, as best i could. But you can remove them if need be.

Hope this helps

Removing the inlet and exhaust manifolds without removing the engine is no easy task. It's not paticularly hard, but it does test your patients!!

Oh and be carefull when removing the exhaust manifold bolts, use plenty of wd40 on them as it's a Bsterd if one snaps!!!

Exhaust bolts are terrible for snapping cause they get heated and cooled so often. Plenty of standard exhaust manifolds on ebay or even performance ones.

Ah I see, you mean the manifold to downpipe bolts. Not sure on the bolt size though buddy, sorry.
