    Not that it applies to your situation but keep in mind a magnet is not a reliable indicator. Some grades of stainless steel are ferrous.

    It will keep your header from breaking welds due to vibration and engine movement under throttle. At least SuperCircuit seems to have done their homework when they designed it. There are a couple of members that have one installed and no one has noted any failure so that's good (unless I missed the post).

    Cool Installed the Headers!

    Okay, got the headers installed. Everything fit except the flange which was crooked. I had to buy different exhaust hangers to lower the back of the exhaust for it to fit right. It runs great. No engine light came on either. Here is a lot of pictures for you all to check out. Also I learned to take out the rusty studs on the engine block to replace with titanium bolts.

    Give us updates on any differences in how it runs, performs and mpg's after you've had a chance to review it.

    I agree. I'd love to hear your thoughts on how it performs.

    Does anyone know if these are still being sold, and how would I get a hold of them without Facebook? I deleted my accounts over a year ago.

    I cannot find any headers readily available for the US. I found some on Lazada but shipping is limited to Southeast Asia.

It has 3 separate pulls on it so you don't know really what is what. I never saw a picture of the stock exhaust manifold, but it does look pretty horrible haha.

    SuperCircuit is a company in Malaysia. I'm going to email them about a price shipped to the US so we have some idea. SpeedLab quoted someone here I think $250 (currently $180 USD) shipped to Australia.

    Here is the email reply from SuperCircuit:



    Mitsubishi Mirage (6th Generation) Header


    Attachment 4747



    Attachment 4748



    blue = stock
    red = Supercircut header
    green = Supercircuit header plus 2ndary CAT removed

    Attachment 4749
    Did you get a new tune or are you driving it just swapped without any changes to the ecu?
