Re: Header ID

Lookin' like Dynomax to me. They should be 1.5" primary tubes into 2.5" collector shorties.

Re: Header ID

They're not great, but they're better than stock manifolds. Header wrap is rarely a good idea.

Re: Header ID

Ran the numbers on the dynomax site and came up with nothing so I have no idea what these things are but they will have to do till next winters modding start cause this year is trans repair and carb rebuild and new air cleaner and other little things. thanks for giving it a shot tho..not sure on which header Im gonna go with but it will ethier be hooker or headman thanks to the sticky at the top.

Re: Header ID

Don't limit yourself to those if you're not scared to drop a couple of bones and want some long tubes. Hooker and Hedman are pretty good choices for shorties, since SLP chopped their thirdgen line. I agree on the header wrap; I've seen pics on this site of headers that rusted through due to the header wrap absorbing water.
'Better than manifolds' (as far as performance) was going to be my response on those dynomax's as well. The reason I say they look like dynomax is because those are the only ones I've seen that have that loop on the header flange (except maybe Summit brand, but those are just reboxed from other manufacturers).
Personally, I drool over those Stainless Works and Doug's long tubes. But then again, they are about twice the price of my Hooker 2055s. Actaully Doug's aren't too bad at about $500.

Re: Header ID

must be nice...here where I am I can't find a set of shorties for under 800 bucks....by the way whats to be had by going with longs tubes over shorties? I like the ceramic coating but I've herd bad things about them chipping but I've herd the painted ones rust out.
