    Headers....

    Are on my car!

    Right side







    Left side







    Left side installed (pic from wheel well)



    These are a direct replacement for stock manifolds!

    There is no good way to put cats in these without compromising the design. Cats will not be an option but can be added to the exhaust behind the headers by any muffler shop if desired.

    3/8" flanges
    1.75" primaries

    All 304 stainless construction

    Made in America

    Price: $1199 plus shipping.

    PM me for orders.

    RWD versions for sure. I sort of doubt they will fit the AWD though.

    Re: Headers....

    Here are a couple more pics









    Install is pretty straightforward. Remove the old manifolds, remove steering shaft (two bolts) install headers. Getting to all the bolts on the headers is not as easy as the stock manifolds but not impossible. The stock oxygen sensors reach the new locations without extensions. I recommend a 13mm swivel socket. Even if you have to buy one it will be worth it.

    I forgot to mention the difference in sound. During normal driving and cruising there is no difference. At half throttle or more deep V8 noises come out! I love it! Quiet at cruise, deep and throaty when you hit it.

    Call me any time tomorrow Kyle.

    I'm in MI, south of Grand Rapids. Take a picture under your car where the front differential and driveshaft go. I'll be able to tell from a couple decent pictures.
