From looking at the pictures, I dont think they will give you any more than 5rwhp. They dont look like they would be worth the money to me, but I guess your dad has the finay say in this. I bet you cant wait to get out of the house and spend as much money as you want on your truck!!!

Look into Edelbrock:

These are the results they claim for an '03 Hemi Ram using a dyno:
"#66693 TES headers 2003 Dodge Hemi 5.7L V8 28 hp 34 ft/lbs. "

That is thier tubular exhaust system....headers and new y-pipe. Part numbers for the '04-05 are 66792/66793.

Had a set of Edelbrock headers on a z-28 I used to have and loved them. When I am ready for headers, I am leaning towards them again.

He said they have to pass emissions. Are the Edelbrock's smog legal? And I wouldn't believe thos dyno numbers until someone installs them and gets a real dyno sheet. I'm sure they will make some power, but those numbers are VERY hard to believe.

"Most Edelbrock Tubular Exhaust System headers have been granted an Executive Order Number from the California Air Resources Board making them street legal on pollution controlled motor vehicles. An Executive Order Number is pending on some applications, call our Factory Tech Line for more information on these numbers. Emissions exemption and a street legal status is granted through an extensive testing process that shows that a device does not reduce the effectiveness of a vehicle's pollution control equipment. "

Most of thier products already have the EO number...I contacted them to inquire about fit, but didn't ask about the EO just yet as I am a few mods away from headers just yet. However, a call to thier tech line would quickly answer the question.

You can do what I recommend to everyone else...Buy a cutout instead. You can get an electric cutout for $200 shipped, and see damn near as much gain as you would with headers. I have one on my truck, and it has been proven on the dyno and at the strip to produce more hp and tq. It isn't smog legal when it's open, but a quick flip of a switch fixes that problen in 3 seconds. One of the best mods I have...and just for reference. Look at my dyno #'s and track times in my signature...That goes to show that the cutout does help.

Gibson headers are going in to my 03, 4.7 quad Thursday...Intake all done and with the headers going in exhaust will be complete. I will let you know.

Electric fan (pullies) and cam will possibly follow!

What you should do is get the Edelbrock TES Ti-Tech coated headers that guy above mentioned. Best bang for the buck when it comes to Headers. You'll have to modify your existing Y-pipe with these because it doesn't come with a y-pipe for your year ram...

Cuto-outs

I have been doing some research on the e-cutous? I see you have the hedman hedders and i was wondering if you like them, build quality?
I hear good and bad about the headers (like everything else) but wanted to hear from someone who has been using them for awhile. The cutout; did you get 1 or 2 - before or after cats?

I have TES's on my 04 and I agree 100%- have not dyno'd yet but the sound my 20's make from a standing start tell mr it wasa good ides. Also, the Hemi engine is supposed LOVE extra exhaust from a tech article I read. (Plus you get to put he infamouse "Edelbrock" decal on your rear window!)

how much did you pay to have it installed? or did you install it yourself?

I love the hedmans. They were cheap in price, but not in quality. The only downside is that they are not coated, but that can be done at your local shop for about $150. I gained 12hp/19tq from these headers on my last dyno. The cutout has been an awesome mod on my truck also. I gained 12hp on the dyno when it was placed after the cat...now it is in front of the cat, and the gains are even greater. I only have 1 cutout ecause I think a single exhaust is best for our trucks. Look in my sig at my short list of mods, and impressive dyno #'s track times. That will show that these mods will work!!

I've had those Gibson's in since x-mas. I love them. Sure, I imagine theres something better, but I needed to make no modifications and the parts fit just right. Shorty headers are known to increase top-end, which is half the reason I went for them and the other reason being that they were well priced. Anyways, truck pulls harder to me(especially in 1 and 2 range), havn't had a leak yet...and hell, the discoloration can kiss my ass - im not building a show truck. Be trading it for 04 Cobra soon :cool:

Not to clear on the h-pipe installation about moving the cats.
Do you mean extend them down to the rear of the truck?
If so how long.

One other thing i was wondering.
I have o2 sensors before and after the cats. Do the cutouts have somewhere to put the sensor into, or do i need to install the cutout after the first sensor?

First thing you have to do is build a custom "crosspipe" that goes from the driver's side manifold pipe to the passenger side manifold pipe. It'll be some custom work. But before that you'll have to move the cats lower to have room for the "crosspipe." The electric cutout will be install ON the crosspipe. Then you're done. You will need o2simulators.com

The "crosspipe" will be installed after the first set of o2 sensors but before the 2nd set of rear o2 sensors. But because you're moving the cats to after the 2nd set of o2 sensors the check engine light will go off because the 2nd set of o2 sensors aren't reading the cats anymore.

hey i was wondering..im looking into saving up for these headers (my dad will only let me get ones that dont void warantee or smog emmissions). im just curious as to whwat kind of power this adds? does anyone have an idea or have these headers? any informatino would be really helpful thanks.

I wouldn't spend your money yet. Nobody makes headers to fit the '04 & '05 4.7L yet. Supposedly Gibson will be releasing some headers for our trucks in the coming weeks. There was a change in the '04 truck that won't allow the earlier headers to fit. Gibson is actually getting ready to release headers for the Hemi, see link.

Not your typical header that's for sure. I don't know what the power improvement is supposed to be? Who knows, maybe Gibson has come up with something new and inovative here.

I am going to wait and see what the ones for the 4.7 look like when they come out.

Wait for the Gibsons...WOW! I had them installed without any problems. A professional fit. I took a while to come back with a reaction because I spent most of the weekend driving around town. I really noticed a difference between 2.5 and 4k rpm. The truck feels lighter (much crisper throttle response) and running noticably cooler. I figure the 5-8 hp as per Air_Ram is pretty accurate. I noticed a sweet deeper rumble tone in the exhaust...not louder, just a true modified sound unlike simply installing a performance muffler. My advice stick it out, save some extra $$ and get the Gibsons! You will love the upgrade and because of its fit never have to worry about them down the road!
