ARH still need a little modification to fit too. But yeah youre better off with arh
Well I can do the fab work myself as long as it nothing crazy. I was just seeing if anyone had done it yet. I am also looking for some better pics to compair the headers. 300. plus a little bit of cutting and welding is way better then 1500.00. I dont need this thing to run 11's just faster then stock. I have a mustang to run the 11's

Well as you are making a set, ill pay you to make another set for me. But the headers from the 300c/charger/magnum flanges will fit, but not sure about the piping

I was looking at the LX forums, and they put some JBA shorties on an AWD mag. so those are the short tube ones you might wanna look into as they fit behind the TC of a LX body.

Then consider all the sensors.. James was explaing to me there are like 2 o2 sensors before each cat, then 2 after, and 2 narrow band AFR sensors too, so thats 6 bungs.

2 high flow cats, or gutted cats, or no cats at all one the midpipes, and bolt them up to the stock flange

I would love for a better option, and have been bugging companies left and right to no avail.

Re: 5.7 Shorty Headers

ohh and these is no need to remove the heads, it can be done without doing so

I would also recommend a wideband and gauge to monitor afr too.

Re: 5.7 Shorty Headers

1500 bucks plus a shit ton of work to install just doesnt seem practical to me. you can get a twin turbo setup for 1500 bucks right now. i know they sound good and from what ive heard they give decent gains, but thats a TON of money. just my opinion.

Gotta pay to play... What you arent considering (twin turbo from where?) is the install of the whole kit

Plus gauges and sensors to monitor it
Plus if it needs a meth pump, nozzle, tank ( if there isnt an intercooler)
Plus a tune which will probably involve dyno time.

I was quoted about 350 to install headers, so when thats all said and done, its about 2100 bucks for headers, install, cats, harnesses, and wideband.

You can run headers without a custom tune, or just get an email tune.

I am not saying headers add the same about of power, but really, a turbo kit isn't "cheap"

Re: 5.7 Shorty Headers

I guess it all goes back to what type of gains you get with the headers and I am eagerly waiting for AM5's dyno session.

Re: 5.7 Shorty Headers

I'd like to know what is involved in 'adapting' a pair of 300/charger 5.7 headers to our chassis...is it just the secondary (collector) flanges? or maybe it comes with intermediate piping and that's what is causing grief? That wouldn't be 'too bad', as you could make a custom Y if that was the only main drawback...I'd like to know if they physically fit in our limited engine bay with respect to the 'frame' rails...we have 0 clearance and I have no clue about those cars and the room available.

Normally 'shorty' headers are kind of a waste of money (esp on something like my GTO that had reltively long runner cast manifolds), but in our case, the manifolds are extremely restrictive and have no runners, so to speak...The 6.1 SRT manifolds at least have some form of 'runner' and bet those would help. I would loooove full length, but with commifornia, don't want to take a chance with smog and such...Besides, $1500 is absolutely ridiculous!

niether option is "cheap" but when you look at hp/dollar it just doesnt seem practicle to me. ive had headers in a couple of my vehicles and they've been a money pit on every single one. on my mustang i had longtubes put in and it sounded great and pulled a noticeable bit harder up top, but when you consider i payed 700 bucks for the headers plus another 150 for the midpipe, plus 400 for installation, plus 60 bucks every couple months to get the bolts tightened, it adds up. and anyone who quoted you 350 for header install on a hemi wk has no idea what they're getting themselves into. they're going to have to jack up the motor, or pull it completly, custom bend a midpipe, plus squeeze there ass into smaller spaces than they'd care to squeeze into. ther's a guy on here that had headers installed and i cant remember exactly what he payed for install but i want to say it was about 800 bucks. dont get me wrong, im not saying you shouldnt get them, hell id love to have headers myself, i'm just throwing this out there.

Re: 5.7 Shorty Headers

It was hemi beast... I dont remember him saying what he spent, but 800 bucks is pretty crazy...

The shop i got a quote from also mentioned they had never done it on my vehicle before, but have for an srt jeep. Not sure why it would cost so much (800) considering that you dont have to pull the heads off.

I'd love for a cheaper alternative than 1500 dollar headers, thats why i fully support trying to fab up your own from the Lx platform headers.

But Id still like to know what twin turbo setup you can get for 1500 bucks specifically for the srt or non srt wk.. Because the universal kits will need double if not triple the fab work.

No doubt about it i would love to do a turbo set up, but there is so much involved

off topic but why not put loctite on your header bolts so they dont loosen?

Re: 5.7 Shorty Headers

if you put loctite on header bolts, and you need to take them out for any reason, ie trans removal, it will be a total nightmare. here is the turbo system i was telling you about. http://www.jeepgarage.org/showthread.php?t=9424

Re: 5.7 Shorty Headers

^^^I wouldn't use loctite, but would anti-seize (for other reasons)...I've used Stage 8 locking fasteners on my 383 'velle engine and never had one loosen Compared to a camaro I had that I must've replaced the gaskets 5X from loose bolts, lol [this was before Stage 8 were around]...I'm sure they make them for just about any application, but if not they're a simple, effective device that is easy to replicate (get some small head bolts and throw on lathe to get a groove about the thickness of an e-clip; make a plate that has a hex opening to match bolt head and that would hit the primary if you were to loosen; the e-clip simply holds on this plate)

Keep in mind with a twin turbo setup, you still need to use a different pair of manifolds (most effective vs. a header to retain the heat for exhaust turbine(s)) and while ours could work, there are better designs that would be more effective, for sure...Then, where do you mount those turbos in the WK? Not too many places, for sure.

To take full advantage of the turbo(s) you of course would want and intercooler, to upgrade the cam, maybe do some head work and all the other goodies that go with it (fuel and control/tuning)...certainly not a trivial matter and definitely not a 'slap on a turbo' thing (I hate when people say that like it's some simple task and all...ricer talk )

Yeah the LX ones are what I am looking into. I am thinking the factory Y-pipe could be modified to fit them and that way I wouldnt have to worry about the cats or the sensors. I am going to try to get up with my uncle to get some measurements off his Challenger RT. That will give me a little more info.
