If my exhaust manifold is 3/8yhs. How long do my header studs need to be?
I'm looking at ARP, BUT my internet won't load their web page, summit says the ARP-400-1404 is for my truck
Jegs is saying ARP-100-1414??
400 is stainless...cost to much.100 is black oxide much nicer price.
Summit doesn't carry the ARP-100-1404 and Jegs doesn't carry the ARP-400-1414.
I want the black oxide of which ever fits. Suggestions??

 

So a quick update for my exhaust.....its hard as ****. We got it all out....except both sides bottom front two studs/nuts.
half the studs came out with the nuts, when putting them back in I should like a locktight? And anti seize for the nuts?

 

The new exhaust is fully installed, sounds wicked awesome! The new Y-pipe wasn't long enough to reach to the driver side (eBay..) but I chopped a Chuck off the old Y-pipe and fit perfectly, and I used the same mounting bracket for it. I had to do a "modifying" on the heat shield around the Y-pipe. And I don't yet have the tips for now it ends at the muffler which just behind the cab, I'm hoping two 3.5-4 tips in front the rear tire will make it a lil less loud inside.
Sorry, no pics of videos yet I don't have a computer so maybe tomorrow.
