The correct answer is yes, a lot of third gen guys actually use second gen manifolds because the third gen manifolds are no good.

The stock elbows on the 3rd gens create a bottle neck where the mounting bolts are recessed into the elbow design at the mounting plate. the squared corners aren't the greatest for flow either. In my opinion, $300 is cheap for increased air flow. The cfm plus and the banks high ram are both good options. depending on your other supporting mods, you should see a mild increase in fuel mileage and even a small hp increase although not vastly noticeable.

I disagree. Don M made a post telling about how back to back dyno pulls showed a loss of about 10 horsepower using an aftermarket intake elbow. I believe it was actually the Banks piece.

Have any facts to back this up. A reputable expert has posted dyno results showing the opposite of this. Im trying to find the post but theres just so many. It might even be on compd.

There is a noticeable HP gain from 1600 to 2000 RPM range from Pusher, CFM, Glacier, etc. IIRC with the CFM it's around 45 HP in this RPM range. Doesn't have an effect on peak HP though.
