    need to know because my passenger side manifold has cracked and has a hole in it. also will extractors make it go limp? ive got a mate that had extractors and took them off because the buick didnt like it.

    You may want the extractors but my local exhaust shop in Nowra did a successful crack repair on my passenger side manifold.
    I think they heated the whole manifold first and buried it in sand or lime to retain the heat after the weld was done so that it cooled really slowly. Didn't cost much but I took it off and took it to them and re-installed it. I also fitted a manifold gasket to give it a little more wriggle room.

    There's still plenty of uncracked units out there to be had at a much cheaper price than fitting extractors. As far as P plate legal is concerned you should have absolutely no issues at all as it will only add a few extra Kw's which won't break the power to weight ratio bank that's for sure. It's not like you are fitting a Turbo or Supercharger etc.

    Sounds like they knew what they were doing.

    Yep we use builders lime at work when annealing before machining. Allows the metal to cool very slowly and avoids rapid contraction.

    Be careful, in NSW, any modification that increases the output of a vehicle makes it a prohibited vehicle as far as P plate drivers are concerned....

    Technically speaking that rule applies to any car in any state, but they tend to turn a blind eye to it generally unless they really want to nail you for something. How they do this is about how the car is presented for compliance by the manufacturer in the first place so in reality you are changing the vehicle as it originally complied and that's their out every time.

    Technically it wouldn't be allowed.
    In all honesty, if the car isn't loud or excessively low then it would barely be noticed.

    But if you want to avoid the conundrums, don't have them painted in some baby blue that stands out.
