    Flowtech headers blow!!!!!

    PLEASE DO NOT BUY THEM!!!!

    the passenger side, didn't line up with the collector, so i cut a little slit on the stock side of the exhaust and had it welded once it was all bolted up, that was it for the passenger side. no more problems.

    the driver side leaks, got new gaskets, leaks, got new gaskets, leaks got new gaskets! i broke two bolts in the process. still leaking, I tried Mr. gasket, Felpro and brand new stock GM. still leak.

    the collectors, flowtech sent some BS fiber gaskets when it needs a crush ring gasket. that was a lesson learned the hard way after constantly trying to torque and re-torque the collector bolts.

    So anyways, enough with the rant, what are my options? Other then new headers or stock exhaust manifolds.

    oh and to top it all off I'm driving across the country in three weeks. So i need to get this fixed ASAP
