Careful anyone recommending headers from SRT wk cause I heard that someone had fitting problems on passenger side and was nightmare. Check out thread on the JeepCommander forum
Sorry for possible misinfo, swear I had a long back and forth w a guy on http://jeepcommander.com/ (should still b a thread) that seemed legit that said he had to do so many modifications to get it to fit his xk that he believed the mods he had to do restricted air flow out of Rt side. Thx. Always good to double check and helpful for me to learn.
@Mark Are you sure? It is the same part number on AllData. I wonder if there is something not detailed about the part for each different LX motor? I even checked the head part number for the 2008 and 2009 motor and it did not change across all 5.7l motors.
It’s not the head that changed. The physical shape of the “truck” manifolds vs car manifolds. The car 6.1 flange will bolt to an suv 5.7 but the pipes and outputs will be totally off.
The driver side is the real pain in the butt. you basically need to pull the motor to use the 6.4 headers. Evan after pulling the motor you still need to flatten a portion of the header to clear the fram rail and steering linkage. It is doable, just not for someone who is not prepared to go full custom
Following.
May be able to fashion some out of PVC…?
Lol, joking aside, I think you may have to have some specifically fabricated for your jeep.
Ha ha wow David that was a knee slapper, PVC!
am ded on incide
Pls save
1 like=1 pray
Thank, Gill @Will.
Lol gill
Alan @Alex
Dumbest things can be so funny, right Gill @Will ?
Ever heard of the singer Vince Will?
@Devin no
He’s an awful singer, similar to Vince Gill.
I’m interested to see what kind of differences for fitment there might be between the Cherokee and commander with the 5.7’s
I have heard that the SRT headers work on the 5.7

Nope
I have the ‘09 6.1 SRT headers on my ‘06 5.7. Super easy to install.
Is this Cherokee or commander?
@Cole installed on my Commander, sourced from ‘09 Grand Cherokee
@David really!?! That’s great info, was there quite a noticeable sound and performance improvement? Do you have any video?
Also I guess I should ask are you referencing aftermarket long tube headers or factory 6.1 srt8 manifolds
@Cole factory headers with maganglow midpipes
@David is this video on youtube
@Cole this is my truck
Not on you tube
Ah I see the video is not working
@Cole reposted the video so it works
Maybe I’m being Facebook dumb but that video still isn’t working for me
@Cole Naw, I had to just repost on a new thread. It was me being FB dumb
After install you will need to buy the srt midpipes or the aftermarket version from magnaflo
The headers have a 3” outlet, which is bigger than the old stock
I’ve done it too. Gotta cut a tab off the trans but it is pretty straight forward. Highly recommended

That was for the srt headers from the 6.4. Those headers have to be modified to fit and there is a ton of other craziness with adjusting the steering
These are the shorty headers you want
I spoke to the owner at American Racing Headers he claims they can make them its on my list
https://americanracingheaders.com/collections/jeep
The mopar headers are actually really good and can be found for $100 on ebay, ect…
Which ones @David?
@Mark 2009 6.1l SRT 8 headers. The ones in the picture I posted
Oh ok i was thinking you were talking about some mopar performance headers I didnt know about
Yep those be the ones I had on a wk 5.7. SRT mid pipe too. I made a custom adapter to go to single 3inch after that
The didn’t see any headers for a Jeep commander on that list @Mark
Grand Cherokee same
These headers are factory to Chrysler 300, Challenger, Magnum, Grand Cherokee, Nitro, Durango for 2008 and 2009 5.7 and 6.1L
Look for them under those cars
and chargers
Wrong, those are specific to jeep 6.1. Other 6.1 model headers will not fit
Cole Ventrone as I said I called them to ask. The WK is listed on their site

These are car SRT manifolds.
These are Jeep SRT manifolds
Surprisingly the cars have more room for the runners. This explains why the look “fuller”.
@Mark I thought the larger ones were for the later 6.1 and 6.4 SRT engines that came after the 2009 generation.
6.4’s definitely do not work for Jeeps
@Mark Yeah those are a super tight fit and took a significant amount of work to get in. Certainly not worth the effort in a Commander

I went back to the Jeep style for a more appropriate flow for what was going into the motor
