When installing a new exhaust manifold, are new bolts/studs required?

bluechrome

No they are not required but Sounds like there pretty sweet

Ok...here is the scoop.

They are NOT ARP...they are something else that Nathan has sourced to stop the loose manifold bolt issue with hot and heavy twins...

He can source them for you...or I could. He has the time to answer the phone now...so give him a call if you want some. I got cut short with him on the phone on my drive home last night talking too much about guns...lol.

thanks Christian. Looks like i might have to get a set when I am up there for Christmas. You going to be around?

cquestad

Yes...come over to the new ranch in Dry Creek and hang out for a beverage of choice and food. My wife and I will be entertaing all week.

Want to shoot a bunch of Ducks? Bring your gun and WARM waders and gear.
I will do a "DTR" hunt for those that are around...lol...Nathan...Big Mark...etc.

I found some 125K psi studs with rolled threads to use with metric flanged lock nuts that lock to the part w/o serrations... gonna try those out & report back.

Ditto on what Christian said above on the manifold-to-head studs from Nathan.

I haven't had to remove mine yet. At the same time nothing has come loose yet. I liberally applied anti-seize during installation so hopefully that will help a bit upon removal.

If your buddy is Justin he is gona get it, but I had a tree fall on my truck 2 days ago so its in the body shop, with the turbo still on it. I am gona run an HTT 62/71/13 for now but only for as long as it takes me to get everything rounded up (and payed for) to get twins. As soon as my truck gets back to me I will pull the turbo that night and send it on its way.

Thanks Christian, I will give Nathan a call when I got time and order a set. I may try and get that way this fall/winter to track down some elk with Shane (time permitting) so we may swing by and say hello.

dieselfan
