Haha, alright man whatever you want. I'm willing to bet the metal plate has a sticky backing that attaches it to the pipe. They probably didn't weld or rivet it on there. If they did, that's idiotic. That's gotta mess with the air flow.
As for the dyno...... it's a ******* metal tube. It's the same shape and size. How can there possibly be a difference in the power output? Like, seriously, that doesn't make any sense! Does injen have a secret "power-magnet" pipe or something that pulls air particles along toward the TB? A mini electric supercharger built into the pipe? I don't see how there can possibly be a difference of more than maybe 1-2 hp between the two (disregarding filters cause of course a K&n is gona help, but Apex'i is beter, and as I mentioned, cheaper)
