    Ive been doing alot of research on Headers for the 3.4L. And Ive gotten alot of mixed answer's. But I want to know if it will be worth the cost and exspense to have them installed, to get the headers? Will I really notice an increase in power or MPG's? I do have a CAI and exhaust, so this would compete the exhaust, but Im just not convinced its a good idea to spend the cash on it....:( HELP!!!!!

    OH!... and what is better quality? JBA or DT or TRD?

    Headers really wake up the 3.4. I think its worth it.

    I know..It makes a larger diff, when SC'ed, but it still shows good gains NA. More mid range and top end. Personally, I say go for it!

    Im still not sure about the install? It seems like a huge PITA. I also dont want to spend 500 bucks to have a shop do it.... this is also why, I dont think its worth getting them.

    Have you considered the TRD headers? Its an easy install. Should only take 4 to 5 hours if you have never done it before.

    oh.. ok. Maybe I can find some for a descent price, bc the TRD's are a little spendy.:)
    I just want a little more power. And im not quite ready to S/C it yet..

    No. Get some Gaskets from Toyota. Your gonna need the ones to mount to the head, and the one for the Y pipe. Also get some Copper RTV. You will be good to go!

    I thaught it came with gaskets.... but if not, I'll make sure to them. Thanks!
    And are the gaskets the dealers have made for the TRD headers?

    It may come with Gaskets, but unless they are Toyota gaskets, I wouldnt trust them. I have had leaks every time when useing off the shelf stuff. No leaks EVER when useing Toyota gaskets.
