Hey, i was just wondering if anyone knows how much the nuts that hold the exhaust manifold on are supposed to be torqued to? Or do you just tighten them up as much as you can? Any help on this subject would be greatly appreciated. Thnx.
Jon
Same as stock manifold?
do NOT tighten them as much as you can as you WILL snap the studs,
27 - 35 ft/lbs
remove them in this order if you dont want to snap a stud and also tigetn them in this order if you want your gasket to seat properly
also obviously buy a new gasket duhh
oh, geeze… thnx that diagram is sweet. but i ended up just doing it before anyone responded to my post, everything seems to be fine now. the noise is gone, but i didn’t take the nuts off and on in that order. will it make a really big difference whether i did or not?

Chances are it won’t but whenever you are tightening something with multiple nuts/bolts you should tighten them in such a way that even pressure is being applied across the whole piece rather than working from side to side.
Heat cycle the manifold and then retorque them.
Buy new manifold nuts. Don’t reuse otherwords they just endup loosing off when tracking the car or running high revs for extended periods of time.
You want to get yourself the ones that have the last thread cross threaded. CT sells them. Figure out the size and thread pitch and go buy 8 new nuts.

i wouldnt get CT ones, theyr shit and will mess up with heat, you need high heat anodized ones, they have provem themselves, I use to use CT nuts and bolts for my exhaust flanges and what would happen is the threads would deform and you cant get the nut off, you can break it lose but than it will just seize, get anodized high heat ones, if your stock ones are fine than reuse them
the point in loosening them in that order is sometimes if you undo all the left ones completely for example, the manifold will pry on the right side making it harder to break them lose and potentialy casuing wrong angle and snaping a stud…
Where do you get your bolts?
do you guys find it really akward to work on? cause when i was doing it yesterday, it was the biggest pain in the arse ever!
