Something to think about. Look at the midrange gains.

It looks like the prototype racing header gives alot more low-end which is much more important on our V6 Auto's then high horsepower since we already have power there. I have yet to see the Prototype header for sale though. All i see is comptech and obx. I hear OBX gets better gains than comptech.......is this true??

 

Just wanted to note that Prototype's dyno was comparing with a Comptech. Check this out: http://www.comptechusa.com/images/dy...Headerplot.pdf

So, the Prototype header is less expensive than comptech AND produces over double the power gains for the majority of the power band. :eh:

Those are some really good gains, especially considering that he was only using a 2 3/8" exhaust. :eh:

 

Not bad. It's nice to know the AV6 engine has some potential, but too bad the car has a horrible 4-speed transmission.
