2wd/4wd header?
thanks for the welcome and the info guys... i was just at a garage today and they said $250 to put it on there im positive i can do it myself... its just the only torch i had is a propane one and i dont wanna get severely stuck ya kno
one thing i was curious about was the vacume lines and the metal tube that come out of my manifold... i was wondering what i should do... just block them off? or is there a special way? i think the metal tube is the egr and its pretty rusted into there... so i guess id take off the square thing it goes into on my carb and make a blcokoff plate
and the other thing i was worried about was the gaskets and my starter the starter is easy enough with a heat sheild wrap... but the gasket i guess ill just double up and glue together considering i have a tube of the copper rtv in my garage
then i was thinking the smaller the exhaust pipe i run the better my fuel economy is going to be.... haha whats your thoughts on this guys? i was kinda thinking to run a dual 2.5 inch pipe at least a foot back from the collectors then y them both into a single 2.5....but for some reason that sounds like it shouldnt work well to me... and id like to stay away from 3 inch pipe... not sure why but it just seems a lil big
thanks for the help and i guess ill order my stuff either tomorrow or monday from summit

well i called up the local truck scrapper on monday and told them to look for some after market intakes/headers.... i figure why drop like 400 on stuff when i can cheap out and do it for 250- 300 .... now i gotta worry about the stuff bein warped hahaha

For something like a 300 a collector length of 24"+ (based on packaging) would be alot better than the 3" looking one in the picture on summit racing

all the extension really needs to be is a piece of pipe off of the collector with a mtaching diameter. heck, a glasspack attached straight to the collector will act like a collector extension if the diameters match. the collector "ends" when the exhaust sees it's first major change in pressure (like stepping down from 2.5 to 2.25 or even stepping UP from 2.5 to 3)

I got a set of Hedman's for my 84 4x 4-speed, then used them on my 75 2wd auto. They fit both vehicles fine. One thing you'll want is a heat shield for the starter ( I used a coffee can), or you'll get good at replacing them.
