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.

I’m interested to see what kind of differences for fitment there might be between the Cherokee and commander with the 5.7’s

@David really!?! That’s great info, was there quite a noticeable sound and performance improvement? Do you have any video?

ColeQuestion author

Also I guess I should ask are you referencing aftermarket long tube headers or factory 6.1 srt8 manifolds

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

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.

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

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

David

Look for them under those cars

and chargers

Wrong, those are specific to jeep 6.1. Other 6.1 model headers will not fit

Mark

Cole Ventrone as I said I called them to ask. The WK is listed on their site

@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.

0
Mark

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.

Mark

These are car SRT manifolds.

Surprisingly the cars have more room for the runners. This explains why the look “fuller”.

David

@Mark I thought the larger ones were for the later 6.1 and 6.4 SRT engines that came after the 2009 generation.

0
Mark

6.4’s definitely do not work for Jeeps

0
David

@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

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

David

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