Ok guys here's another cracked manifold question. My T is 2wd non tow gears and has 117k and the mileage is starting to drop off. A little background. I have a maxtrac 4inch spindle lift with a 1.5 inch spacer with bills on the middle perch. Also have 35x12.50r20 Aturro mts. Hate them there impossible to balance. Anyway my milage used to hover around 12-12.5. Now it's at 10-10.5. Im pretty positive the drivers side is done.
I can't any information on these. They look legit and the price is so cheap I just can't pass it up. Anyone use these or have any feedback back for me would be great before I pull the trigger.

They're probably Chinese knockoff JBA headers. Try them out and let us know how they fit. If you do, go with OEM Nissan gaskets.

Hmm just read a bunch of the sellers feedback. Not specifically for the titan ones but so many people said they were junk. I think I'll wait and save for the jba. Can't decide on long tubes or the shorties. I'm in socal so leaning towards the shorties.

Check out Cajun b-pipes. They have a manifold fix kit that includes the headers, the secondary pipes that go after the headers (which you'll need), and uprev so you can tune it. I think their package price is a hair cheaper than if you sources them all by themselves.

The 4x4 models are the worst, the diff gets in the way and makes it a pain to work around.

I laughed when my dealership quoted me 455 Canadian for install. I never said anything other then sound good.

With the cracked manifold is there a distinguished sound that says yup...that's the manifold! I ask because the noise I'm hearing is a buzzing sound which my buddy at Nissan over the phone said it sounds like the belts or a pulley? But wondering maybe it's the common manifold leak I keep reading about? Or the oil filter?

So no go with these DNA Headers huh?

The cracked manifold sound is a ticking-puff-of-air sound when the engine is running. It will speed up when your RPMs are higher and if you're on the highway for a while, the sound might seem to disappear because the manifolds will heat up and the crack will shrink a bit. Next time you're at a stop, roll down your windows and step on the gas to get the RPMs up and listen for the ticking.

Could it sound like crickets?

I don't believe so. Are you hearing more of a high pitched squeaking noise? That could be something with the belt. The sound you hear with a cracked manifold is just air escaping through the crack so it likely wouldn't be making a squeaking noise as well

Mine didn't tick, it was more of a flutter noise is the best I could describe it

When I did my research a couple years ago mostly everyone described as a ticking but I agree it's more of a puff of air sound. But it is a very rapid puff so I can see where the tick description came from.
