    Cats need replacement, anyone know exhaust manifold torque values?

    So, my 06 V8 is throwing codes for the cats, now starting to exhibit "clogged" symptoms. I will R&R this weekend. Does anyone know the exhaust manifold bolts torque values?

    Didn't the 06 cats get covered by the extended warranty? Or was that only 05?

    Also, it says to discard the old bolts in the procedure, but not the nuts. And replace studs as necessary. Not sure if it comes with ne hardware when you buy it. Also says to use new gaskets.


    Tighten the exhaust manifold studs to 6 Nm (53 inch lbs.) .
    Tighten the exhaust manifold nuts to 25 Nm (18 ft. lbs.) .
    Tighten the exhaust manifold bolts to 25 Nm (18 ft. lbs.) .

    Great, thanks. Yes it comes with new studs, manifold gasket and collector gasket.
    BTW, how I'd become a "dues paying" member?

    Re-phrase that, how do I become a dues paying member

    Yeah only with fighter jets if you overlook something when you're turning wrenches, no big deal right?
