I have the new MBRP cat back exhaust system and wanted to get some input on which long tube header system would be the best for my setup? I am looking for maximum HP.

Kooks or JBA headers with high flow midpipes. You can't go wrong with either system.

What kind of HP gains with Kooks and JBA? Online Kooks claims 20-35HP gains depending on the vehicle.

^^^^^
Realistically you can probably expect a 15 rwhp gain from long tube headers on an SRT. You will probably get better results on an R/T because of the restriction caused by the stock exhaust manifold.

Kooks or American Racing 1 7/8 long tubes if you are not concerned about passing emisions test.

Kooks all the way. Had execellent service with them.

I have american racing headers with high flow cats and mbrp cat back on my srt and could not be happier. It is an amazing combo, sounds great and i picked up a little power along the way. You would not be dissapointed in that combo.
