Default ATP Exhaust Manifold.

The search function didn't yield much on this particular manifold. The manufacturer is ATP no doubt. Wondering if anyone has one hooked up, or how they fit and run.

it's APN, and yes, I have one in my jeep. been running it over a year and love it. It clears the 98 and older intake manifold just fine, but I had to do some clearancing on my 99 manifold. Sounds great, performs great.

The one you are looking at off rockauto.com is $197 (which doesn't include shipping). The APN headers from ineedparts.com are $180 to your door.

I'm sorry... Maybe I meant the one from Amazon. Says ATP as the manufacture.

Amazon.com: ATP 101212 Exhaust Manifold: Automotive Amazon.com: ATP 101212 Exhaust Manifold: Automotive

Also, has anyone Dyno'd a manifold of this design? What are the gains offered over stock design?

Alright so any noticeable power gains after install as opposed to the stock design manifold?

It gives a little more torque and a better tone. Its not an amazing difference though.
