    Collector Gaskets

    If you go with long tube / mid lenght headers, do yourself a favor and get decent collector gaskets. Last week I took The Defyant Marauder to the track Thread here. While making a run, I blew out a collector gasket.

    The pic below shows whats left of the cheepo gaskets comparable to the standard ones that come from Kooks. When I unbolted the x-pipe, this is what fell out! Kinda crappy considering I spent over a grand for these headers and other componants...

    It still surprises me that Kooks still uses the standard 3 bolt flat flange collector, considering there ate much better sealing methods. But if you have to use it, get a set of either copper or aluminum gaskets.

    I forgot to mention that! I put a set of Mr. Gasket copper gaskets in. I knew these were crap when I replaced the crappy kooks gaskets when they blew last year. I've had these copper ones in the glove box - waiting!



    BTW Surge, PM or email next time your down this way at Cecil Dragway.

    I have been using Mr Gasket Ultra-Seal collector gaskets and have never had one blow out (if the bolts are tight). However, unlike the copper and aluminum ones, they are NOT reuseable.
    Thanks to Darrin @ BC Automotive:
    $1800 and it was worse than when he started!

    Nick has always suggested using copper gaskets.

    Summit Racing $1.98 each.

    I blew mine out on CJ's dyno in the fall of '04.

    DON'T QUOTE ME ON THE PRICE...A DOLLAR NINETY EIGHTY SOUNDED GOOD.

    I just took BillyG's car apart and found the gaskets supplied with the Kooks kit still holding their own, 50,000 miles later.
