Bolt-on performance is available with these quality, affordable Headers. Starting with 3/8"-thick steel plate and 1-3/4"-diameter carbon steel alloy tubing, each header is precision-crafted to insure proper fit and seal. The mandrel-bent tubing insures maximum flow to the 3"-diameter collector and on into the mandrel-bent Y-pipe (Not Included). These headers replace the stock cast iron exhaust manifolds and have provisions for all smog and engine management hook-ups. These headers also includes fasteners and gaskets. As well as wire extensions for the O2 Sensors.
