XK 4.7L headers

Seriously...does anyone make them for our engine? I search and search and all I find is listings that say headers and exhaust but all options on headers are null an void.

I have an exhaust leak at my manifolds and rather then spend 200 every 12-20k id rather just replace the entire manifold with a header and hope that fixes the issue.

These are about the only ones I could find when i was lookin' around a bit ago. Never followed up for specific fitment, but after selecting '06 Commander 4.7 and searching on "header" this is one of the few places that actually lists any parts - it even says "Tight Tuck Header for Mopar Small Block Engine" which gives me hope...

looks like these guys might have info - just an assumption based on the assortment of parts.

I replaced the manifold on a 460 engine with headers and had to retorque them several times. Headers can be a pain sometimes especially if the bolts are hard to get to to retighten. I did use blue thread locker and they still needed to be retightened. The 460 truck engine is known for warping manifolds especially after climbing a long grade and then cooling quickly going downhill, but the headers were even more of a pain to keep tight. Just a comment that headers might not always require less maintenance than the heavier stock cast exhaust manifold.

Yeah I had 2 broken bolts on mine last year replaced, the dealer said it was something they'd seen before.

I never actually got them but you can't look for Jeep, you have to look for Dodge. The Throttle Body spacer is for a Dodge 4.7L and there were a few headers I found (BBK was one I think). Not sure how differently they would fit but would probably work

Same issue here with my 06 Commander (V8 4.7l), manifold leak, repaired twice already and this time it looks like a rear bolts failure. Anyways been looking to fix the problem permanently this time and to gain some power at the same time. Never found aftermarket headers for the Commander 4.7l.

I've just contacted Gibson and asked them for a combo, headers and exhaust line..I'll keep you posted, hopefully I'll get a positive response.

Sounds like this is a common problem with our trucks, I have to have the same thing done now.

I have a stainless catback exhaust available but no headers for this one. Not sure if the 4.7 Dodge ones would fit. If you are interested in this system, it sells for $546.81. Let me know if you have any o0ther questions
