    Customers say

    Customers like the quality, fit, appearance, value, and performance of the engine exhaust pipe. For example, they mention it's very well built, sits perfectly on top of the carburetor, and has a good finish. That said, some say it works well on a blow through application and for a N/A engine.

    Just the Carburetor hat I was looking for.
    5 Stars
    Just the Carburetor hat I was looking for.
    Cast aluminum construction, so you will need a Dremel to cut the pieces of casting flash off of the ID of the Carb hat.Pretty good looking to compliment the rest of the chrome ducting I had fabbed up previously.Still a bit on the expensive side, considering the slop, the hat would slide around even on top of a carburetor mounting flange of 5 1/8.When bolted down, looks good and no shimmy.

    Reviewed in Mexico on October 7, 2022
    La pieza es de aluminio sólido, muy buen acabado, pulido y venía bien empacada. Una vez ya instalada se ve magnífica y sienta perfecto en la base del carburador, en este caso uso un Holley 4412 de 500cfm. Aunque es muy probable que se requiera algún tubo/acoples adicionales para alejar más el filtro de aire. En mi caso tuve que hacer esto último porque el cofre no cerraba bien porque pegaba en el diámetro del filtro, sin embargo ya con la extensión quedó perfecto. Es una pieza bastante recomendable para los vehículos carburado ya que originalmente con el filtro redondo absorben aire "caliente" de los manifolds y en cambio usando esto permite una captación de aire más fresco. Definitivamente sí la recomiendo. Saludos
