    Patriot Exhaust H8474 Details

    Nostalgia-style street rods are hotter than ever, and nothing gives your vintage rod that authentic dry lakes competition look like a set of lakester headers. The exposed flathead Ford V8 lakester header works great on rods without hoods, but we’ve also seen them peeking through carefully trimmed hood sides. The headers have flanges so you can connect them to a muffled under-car exhaust when the end plates are on.

    • 3-1/2" diameter x 22" long cone
    • 1-3/4" primaries
    • Includes flange to connect 2” exhaust pipe
    • Removable end plates allow you to run open headers with ease
    • Includes gaskets and mounting hardware
    • Black Hi-temp paint finish

    NOTE: Turn-outs NOT included. Headers come with end plates, but the turn outs are sold seperately.

     

    Primary tube lengths (from front of flange to the backside of the tube) are 6", 7-3/4", 9-1/2" from front to rear.Primary tube lengths (from front of flange to the backside of the tube) are 6", 7-3/4", 9-1/2" from front to rear.

    Will they fit on a 40 Ford PU? Will these fit inside the front fenders? I'm thinking of building headers that exit after the front wheels. I know that I would have to trim the inner fenders. I have a Mustang II front suspension, not stock, and rack & pinion steering
