i figure everyone already knows about the pre cat.. im just posting for the newer than me folks(if there is any). cx racing makes a header, its cheaper than most, and bolts up to the block good.but , if like me the bolts on the bottom of the pre cat were rusted to the point where they all broke off...the bottom part of the header has a different thread than the factory pre cat so the auto part store pieces wont thread through the header... but imma go to lowes and get the bolts that fit right to the mid pipe / header... and since there is no factory flex pipe u need the springs

yea, you can get bolts at the hardware stores, there's even better bolts there to choose from, galvanized, stainless, etc. dont forget to put a new donut gasket on as well.
