Re: 5.7 Shorty Headers

Keep us posted, please. I am very interested in the outcome and options.

As a side question, say the LX headers work and are CARB approved...do you think it would be acceptable to the smog guy? Being it's CA, I would bet it is voided as soon as it's put into something else, but only thing have to worry about is a visual, but good luck seeing down in there, ha ha.

Not twin turbo and 1500 without turbo...

I told myself if i win the forged rotating assembly on ebay right now, I am going to buy this via credit and pay it off over a few months because they are both smoking deals, but yeah.

That is a good point you have there about the factory mid pipes, I didnt consider this, even though they arent 304 stainless, they are 3in diameter and would still flow more than the crap exhaust manifolds we have. Maybe even gut the cats and add an adjustable O2 sensor..

Very interested now

Keep the comments coming, food for thought

Hate to burst the bubble, but i dont think its happening, i am 95% sure they arent CARB approved...

Ive been wrong in the past though

Re: 5.7 Shorty Headers

So how much different is srt engine layout vs hemi? I thought I read that the main difference was the shape of the exhaust holes on engine block but other than that there was not much more.

LTs are PIA to install into anything, not just Jeeps. I remember when I installed a set on my car, I spent about half of a day trying to get oil lines back into steering rack that I had to drop to get the headers in in the first place. But now, looking back, it was so worth it.

Also LTs will generally significantly outperform shorties and even mid-length headers.

The high price tag is also due to headers being made out of stainless steel. They dont rust and look great year after year. Just something to consider before you opt out to buy a cheaper, non ss set...

The layout isnt that much different. How ARH headers makes the 5.7 long tubes is by taking the exact tubes as the SRT, and just put a 5.7 flange on them.

You have to beat on the trans pan to make them work because the difference in transmissions between the two.

I've had an email chain with BBK this last week, I might be getting a set of LX shorty headers to see how they bolt up. If all works out, we will have some great options out there.

Re: 5.7 Shorty Headers

ARH needs to make some direct bolt-on headers for the 5.7. If they build it, i will buy

Re: 5.7 Shorty Headers

Ok from what i understand, the problem using the AR SRT8 headers is the transmition, i know that the 6.1 Hemi uses 2WD Danna 44 (226RBI) its that correct? the problem is with the 4X4 front diff?, so if there a 5.7 Hemi 2WD that use the same Danna 44 like the 6.1, i can use the AR SRT8 Headers, without problem??

Re: 5.7 Shorty Headers

So basically ARH is the only one who currently makes headers or the 5.7? I thought there would be other companies by now. $1500 is just crazy. I guess headers are out. The Gibson exhaust will have to do for Pop.

Re: 5.7 Shorty Headers

I wonder if the 5.7 manifolds have any material worth porting. A gasket-match and cleaning up rough spots in the casting, along with perhaps a coating would go a long way. Provided the manifolds themselves werent warped, there would be no fitment issues, and installation in comparison to the AR headers would be easier.

Re: 5.7 Shorty Headers

Ryan, that actually sounds pretty good. I think you would need an extrude hone process to really open up any area, and the internal coating sounds good too. The question is, since it is still a manifold and every thing (all the ports) come together in a short distance the gains may be minimal for the amount of work, let alone R&D.

The stock manifolds are cast iron aren't they, or are they steel? I have looked at Pops truck to see.
