Look great, good cheap option, would like to see how well they do after a few good heat cycles too. A lot of the forums about the headers for the 4.7 basically tell you to avoid everything if it's not great SS or Ceramic coated, or tell you to spend the money elsewhere because of the undocumented dyno gains per the cost of the headers and any add muffler shop costs if you went that route.

martin, great information. have a 03 club cab 2wd slt, cherry red. i live in kansas- yes the rust belt. already went to electric cooling fan, new lifters, new sryle rockers, full duals , performance cats, flowmaster with x pipe. their is not a pick a part within 100 miles of me. i'm 67 and use a walker to get around, but i still love driving my little truck. if you run into a set of the 17 wheels that were a factory option, and a set of 08 cams n springs i really could use a little help. also i was watching you pull the gm 6 cylinder superchargers and wondered if you had given any thought of modifying the mounting plate/manifold to fit over the valley on the 4.7? oh i am willing to joyfully pay for the parts and your time if you can help. thanks jeff

I found a y-pipe on Rock Auto that has the single cat. I have a 2001 Dakota QC with the 4.7 and I have these exact same headers. I haven't installed either the headers or catalytic converter (y-pipe), yet. My only concern is the fitting from the header to the y-pipe. There seems to be a very small amount of overlap to seal it. I love your videos. Keep up the good work.

I got a set of DNA long tubes for my 06 300C hemi, paid just under $200 Canadian about 4-5 years ago. Very satisfied with the quality and installation being in such a cramped engine bay. My only complaint is the supplied gaskets which are garbage not even 3k (kilometers) and had one fail, i put on some oem ones and haven't had any issues, they sound amazing too. Super happy I saved my money compared to the much higher priced ones from the competition I was tempted to buy these for my 03 ram but I don't know if they will fit since they say its for an 04 and up ram which is strange because there's no visable difference compared to the 02 or 03 compared to the 04. The suspension wasn't changed on the rams till 06 with the face-lift rams utilizing the front coils. Been wanting to make some long tubes for the 4.7 because I don't think anyone makes them

I would think these DNA headers would fit your Ram.. Yeah, the only company that makes long tube headers for the 4.7 is Doug Thorley, and they are only made to fit the Jeep Grand Cherokee WJ.

Think they will work with the factory crossover and H02 sensors for the Durango? Wish they had something for the Jeep GC. I'm doing a HO conversion, VIN N to Vin J and would prefer some sort of shorty factory header to the stock manifolds. I want it to breath so I can use the AirRam adaptors and put the Eaton SC from the Mustang on top. Great Video! Thank you for "pioneering" these! Edit: My 2000 Durango 4X4 SLT 4.7/545RFE code "N" for North East US sale doesn't have the pre-cats. There is only the large crossover and a fat full size cat after the Y pipe goes into one. Before the intermediate pipe there is an upstream H02, the Catalyst and a post cat H02. Maybe that crossover should work off the shelf, or give you something to model off of. Cheers to you, Martin!

Love your video, I've been on the fence about getting a set of headers for my 2004 Dakota 4.7. I think I might get a set of these. I know I will need to have the exhaust ran custom from the headers back, but by chance do those headers line up to the factory pipes on the truck? Also a tip for those header bolts which I agree with changing them to grade 8. First thing when you had that package of bolts I was thinking low grade because they weren't dark colored like high carbon steel. I would put anti-seize anti- galling compound on the threads, being dissimilar metals, aluminum and steel. Same with spark plugs . 👍👍👍

Same, here. Especially the Chinesium. "SS304 rated" but I'm still on the fence of doing it, for the bit of power you might gain (butt dyno) because s lot of the forums talked about it being a 3hr job to remove the stock headers and swap, but never show any dyno before/afters. Plus not everyone can do a header swap in their garage. So figure a couple hundred bucks at a muffler shop to hope they last long enough to be worth the headache, if you or they don't break any muffler bolts getting the broke free from your 20 year old motor. I'd rather save the funds for whenever the current 4.7 decides to need work or depending on parts:cost just do the Holley Hemi swap or get a 360 Mag for it.

A reversible drill and drill bit will help get it out as well as screw extractor or Easy Out as they are called. Use a center punch tool to give the pit a hole to start out and will keep it centered so you can drill the hole in the center. Some mild heat from a Mapp torch would likely help as well, not too much the head is aluminum. You can pull the inner fenders on both sides and that makes it easier with the wheel/tire off to access the exhaust manifold bolts and studs/ heat shield nuts on both sides. Good Luck.

My truck has CARB approved headers(not sure of the manufactuer) my father installed (I've inheareted this '02SLT Quadcab) at some point. There is a CARB(California Air Resources Board) exempt tag welded to the headers, so maybe that is what the tech is looking for. I've never been asked about them. With that said, we even have CA specific cats that you "must" use. They apparently have more palladium or platinum in them and cost at least twice as much. They are looking for a specific number on the main cat and maybe the pre-cats(but those are very difficult to see so they usually don't look at those). I have been called out on not having the "correct" cat when I had a pre cat go bad and replaced the entire system with a 49 state version. Though is passed with flying colors, they faild me. Only the pre cat was bad, so I cut the good CA main cat off and spliced it back in the system. Went back and tested again and they said nothing...oh and the sniffer numbers did not change. Now they don't even do a sniffer test. OBDII only and they are just looking for rediness "ok" and no CEL. This state is a nightmare and only getting worse.

Will these fit on a 08 dakota 4.7?

If that is the newer 4.7 with the dual spark plugs per cylinder then no it will not fit.

Would these work on a 2008 4.7

unfortunately no in '08 they revamped the cylinder heads and changed the bolt pattern for the exhaust manifolds. Thank you for watching.
