I’m the process of taking the manifolds of my dodge 1500 4x4 2010
I was to get the ARH 1-3/4 long tube with catted mid pipes. I’ll be doing a custom tune a custom tune Jay green. I already have the cold air intake, moes 87 throttle body, carven exhaust, with the Diablo canned 91 tune so far. Where is the best place to order those? Is Nick got exhaust still on here ? I tried to call Moe’s performance , but they must be busy, only responding to emails right now. Any information will be greatly appreciated.

From someone who has 1 3/4 long tubes. Get the 1 7/8's. Every hemi engine dyno I've seen so far has gains over the 3/4 without loss a anywhere.

Now for me the cost to buy a second set of headers for only a few more HP doesn't make sense but if I could do it over again this is the advice I offer you.

Do you have any links to share with the dyno comparisons? I am interested in checking this out and see also how the tq looks. I have not seen a benefit from the 1-7/8" unless the truck is supercharged or built motor. Not saying I don't believe it, I just haven't seen it. From what I have seen 1-3/4" is more than adequate for a bolt ons truck. If there is info stating different I want to check it out!

When I have time I'll have to search his channel more. The 1st couple I checked out are on motors that are cammed for higher rpm hp which would makes sense for the 1-7/8" to make more power. I really wanna see a stock engine with stock cam and how they compare. As the few scenarios I have seen show the 1-7/8" doesnt pay for a truck that will be used as a daily and may tow. The lower end tq loss isnt worth the smaller peak hp.

I will check his channel out and try to find different results. I have watched his vids before. Good channel

Couple of things got me in this article after rereading it. The dyno graph shows 1 7/8 final header dyno which is a typo. They are intact 1 3/4 headers vs 1 5/8.
