    454 and 502's use the same exhaust. There was a nice set of solid stainless on E-Bay.

    Thanks guys. I am looking for an aluminum performance manifolds like a Stainless Marine or Dana or even Revolution. Any help would be great. I don't have a ton of money to spend which is why I was hoping to find a decent used set. Thanks again

    I personally don't trust used manifolds.

    I bought a set of as-new take-offs when I bought my Baja in 97. I replaced them in 2000 as they rusted apart. Once a manifold is used in salt the process begins so if they sat for 2 years, most likely still gonna last only the 5 or so we get in salt. Fresh is another story.

    If you change your mind I bought my new GLM's to my door for $305/pr a couple months ago....shoot me an e-mail for his number.

    Revolution Marine Update

    on 1-5-12 I contacted Revolution Marine after reading about their SBC exhaust manifolds. I am looking for a set for my 406 build.

    I received this reply. Unfortunate, because I have read many good things about their exhaust.

    Hi Bill,
    VERY nice looking Donzi! Sorry to inform you that we no longer offer our exhaust systems for sale.

    Thanks,
