Anyways, I see that its a RB street header; but I'm wondering if there will be enough back pressure to open those ports if there is a more free flowing exhaust, such as a full RB street exhaust...

No my car is bright red, but I have seen that tan one as well. He lives somewhere off of Matlock I'm fairly certain. The location of the fitting gives it more access to high velocity exhaust gasses straight from the port, so its not so much about backpressure but just outright exhaust force, that's what I read. Seems to make sense to me.
