New header, is this the right one?

http://www.ebay.com/itm/New-Exhaust-...ASport%7CEnginLooking into getting a new header and im wondering if this one on ebay is the best one to not crack. Been doing my research and found that these kind with the 2 flexible couplings is the best for it. True or not?

Also wondering if its best on gain or is any gain im getting with aftermarket like the banks revolver not worth it? Anyone have banks revolver and have an opinion or experience with it?


Let me know if that links works or not. Appreciate any help as always!

I'm in the same boat you are with the cracked manifold.

I am just biding time until I either work up the courage to change it myself or save the cash to have it done for me.

I would think the stock style would have the same flaw that led to the current cracking.

Thats what i was thinking but the stock doesn't have the flexible coulings on the 2 outside pipes like the one id found, those are what is suppose to stop the cracking, Supposedly. Also thinking that upgrade to a manifold type might work but not sure about it...

The first one is for the 6 cylinder engines, the second is for the 4 cylinder engine. Which do you have? Since your header is cracked I'm betting your engine is the 6.

The ebay one is the one I just installed and can't complain one bit about it. I couldn't believe the quality for $80, but when it arrived and i had it in my hands, I saw right away it was heavy and had quality welds.

But… definitely don't use the gasket that comes with it, pick up a Mopar one.

Getting ready for a turbo I just installed the banks torque tube headers, Magnaflow cat assembly, Magnaflow performance cat back exhaust, new O2 sensors, and new plugs.

The butt dyno noticed a decent improvement but I'll tell you headers alone won't gain you much as the stockers are fairly efficient. If the originals are cracked then go for some good after markets but understand they can crack too.

Thats what ive always heard the gain isnt much on aftermarket exhaust system components, thats why im probably just going with stock.

Personally I wouldn't bet on there being any significant difference between the OE headers (and they are true headers), and catalytic converter and their aftermarket versions.

Not to mention that between Banks and Borla, both of their standard headers crack just as readily as the early TJ's header did. The only one from either of those two brands that doesn't crack is the Banks Revolver header that was introduced several years to address the cracking issue.

i was looking into the revolver but the price just didnt seem to justify the gain, if there is any.
