    Top Quality Construction
    BBK Performance headers are made from 1-3/4" CNC-machined mandrel bent tubing with 3/8" thick die-stamped flanges. These headers are pressure tested to ensure leak free performance. All required gaskets and hardware included.

    Y-Pipe Fitment
    The 2-piece y-pipe bolts onto the header collectors and extends back to the transmission crossmember to terminate in the best location to adapt and bolt up to the rest of your OEM or aftermarket exhaust system. The y-pipe terminates with the tubes against each other so you can merge them into one or continue them dual all the way back.
