Jeep Commander Hemi headers and lift?

Hi guys, and gals (and non binary types...)!

Looking for advice on upgrading/fixing some bounce and an exhaust leak.

First of all the Jeep has a manifold leak, and I would like to make it a little better than stock. A couple issues being that the stock system manifolds are prone to cracking and warping, and the stock bolts are prone to breaking.

I've been told by an exhaust place that a bolt upgrade will just make the manifolds more likely to crack. Not sure about that, but those are his thoughts on it.

I would like a little more performance and put in some shorty headers with better locking bolts. After a long lived mid-range heavy boost in performance without breaking the bank. I'm thinking that the individual runners will put less strain on bolts, and be less failure prone. Sounds like somewhat of a heat issue, I'm told.

Not sure of how often the manifolds warp, crack, and bolts break but it seems to be a pretty common problem. Didn't want to replace a problem with the same issue and just have a stock system.

The issue I'm having is finding something that fits. It seems nobody does it?
Seems like it would be pretty similar to the Cherokee, but I've heard there is less clearance for headers on the Commander? Stuff for the smaller V8, but having trouble finding direct fit for the big one.

On to the suspension. The Jeep has quite a bit of bounce to it, so needs new struts. While I'm at it, I'd like to put in some useable clearance and load handling. Don't want to strain the strain the CVs so I would just do a mild suspension lift of a couple inches, with some Old Man Emu springs. I saw these available just on their own. I believe that I saw them before as more of a "system" with some upgraded struts.

Is it advisable to go to different struts, or it OEM decent? Will it matter that the spring will be extending the shock another 2 inches, or is that mild enough to not really make a difference? But if I'm having it done anyway, I'm certainly not opposed to going to a more capable strut. I'm such a suspension N00b...

Will I need anything else, as far as longer lines, etc?

Thanks all!

good luck with that exhaust leak. broken manifold bolts are a bitch to repair on commanders.

Thanks. This is the "Wife's vehicle" so she wouldn't be too thrilled watching me swear under her vehicle, and then drinking it out for a good week... So it'll be a problem for the pros.

For the lift, I think I go with the complete OME kit from Rocky Road. Sounds hard to beat. Comes with a front spacer to level it; anyone know whether I can use the same in the back to give it back the nose down stance?

Any recommendations either way on going to stronger bolts, new manifolds even if the old ones look fine, different gaskets?

Looking more and more like it will end up being stock manifolds.

Sounds more, and more like I'm stuck with the manifolds.

Decided on the OME deluxe kit. Has everything wanted and needed for a complete system. On sale right now, and on it's way!
