headers for 09
 

does anybody know of longtube headers for the 09 f150's The dynatech kit from troyerperformance hasnt been tested and they dont know when they will get the chance. also if there isnt any what is the main difference in longtube headers and shorty headers performance wise. I know the longtube are better but how much.

Longtubes allow each cylinder to push the exhaust out more equally.
Shorties are just a prettier version of the cast exhaust manifold.
