Have you considered doing the same test with an rbb? Since the RBB does not have the plastic box on the back, you may be able to squeeze a little more out of the porting. I happen to have one I didn't use in my build. PM me, maybe I can make this more worth it for you. Just do a before and after porting with the rbb.

It is the 06+ TSX manifold... It is very comprable to the RTB, but with the plastic chamber, you may have a harder time getting it to flow better. The following threadhas mucho info on this subject.... Including full on picture comparison between the 2. I would believe the resonator chamber on the back would have to be reshaped to compliment the port job you get. I may be wrong though. It would provide more air from idle, but being a hole on the back of the mani it has to create some vorticies the would hinder its capability to flow its maximum potential. And BTW, I have the RTB manifold too, so sont buy anything from the dealer as I can save you some dough and need to get rid of the parts.

I can check at the shop, but it is the correct manifold for the 2007 up years with the dbw. I was going to use it in my build but went with the RBC instead because it is turbo. I can get you some pictures as well..

It was what I had at the moment... Works well though... Enjoy, and im looking forward to seeing the results!
