Many thanks to Vividracing for sending me the Agency Power Headers, it decreased the drone when driving on the freeway, much more high end power, lost a bit of low end grunt, but boy did it make up for it in throttle response. Sound isnt louder (wish it was) but is defintely much deeper .

Sorry for the poor quality pic, didnt have my cam, just my phone, and with the pic above, the left is OE and the right is the new header, sorry for the glare, but they are pretty sweet.

 

Cool; thanks for sharing.
