Sounds like it's near the cat but I can't tell. What is more likely to be going out at this many miles? It's the off-road v8. 2005 and 180000 miles. I've seen a lot have manifold cracks but I figured that's more early on? Maybe just a gasket?

Bet its the manifolds

LikEly manifolds. It's just as much work to change the gasket as it is to change the manifold, just so you are aware. Manifolds are a bad design. Some fail early, others seem to hang on a while longer, but will eventually go. I say you got your monies worth...

Yah I was expecting to hear that. What do you guys recommend I replace them with? Are there any headers that may be around the same pricing as the manifolds?

I'm a little short on money at the moment.

JBA longtubes are the best replacement, can get a pair from cajunbpipes for about half the price of a single OEM manifold.

Is it the stainless steel jba long tubes for $450? This is sweet there's no reason to get a manifold at that price, and I already have it chipped too. I don't have uprev though will any other work fine? Will these remove the cats? I don't have emissions so I'm not worried, just curious.

Yes it will remove the cats (primaries, not the secondaries), and you will need Uprev, nothing else will adjust the AFR's properly for headers.

Ah, theres no way I could afford uprev right now. All I have is the superchips cortex.

You can sell the superchips and put that money towards the Uprev purchase as well

I can guarantee everyone on here will recommend the Cajun fix (headers + b-pipes + UpRev), and for good reason. Replacement manifolds still aren't cheap, and you're eventually going to run into the same problem again (you don't want to do the swap twice). I have the same truck as you (05 Off Road) but didn't make it nearly as long. I did the Cajun fix last summer and was all-in for around $2k (I did JBA long tubes, Cajun catted b-pipes, JBA catback, and UpRev). The process isn't fun, but it's definitely worth it for a permanent fix and some extra HP :smile:

Granted like I said the extra 600 I wouldn't be able to afford. Though I would like to, if I had the money i would have probably already done it.

However, to update, I thought I would hop under there and look around to see if I could see the cracks in the manifolds, I couldn't see any but conveniently looked to the back and saw that one of the welds had broke loose, the whole pipe that crosses under the trans was broke, maybe i hit a rock or bottomed it out on something, not sure, maybe it just rusted and broke, but I had it rewelded and everything is good now. Must have been cracked for a while cause its more quite than it used to be lol. $65 total.

Thanks for all the responses!

EXACTLY!!!! My 2005 cracked at 92K mile now im at 190K with headers. DO NOT put another manifold on this truck unless you want the labor to fix it again in a years time. A set of cheap Dormans will run you $800-1000, a single Maganflow manifold is $900 and will fail as well. Its a design flaw so the best way to fix it is JBA LT headers and Uprev. If you have emissions a set of catted Cajun bpipes needed as well. The Bpipes are not necessary at first but sure wake the truck up with the other two parts. Cajun Bpipes | shreveport, LA 71129 has the entire packages for this issue.

Anyone in MA south shore area know a shop that will install Cajun set up?
