just curious about a ballpark figure.

i recent purchased a 99 eddie bauer expediton with 5.4 v8...i have added a k&n drop-in and a 3" inch catback with magnaflow muffler...

i can feel the performance difference around town and especially on the freeway, i was wondering if anyone had an estimate of the hp added would be...

i know the rated hp is something like 260 stock with 295lb-ft torque, but how much has my setup added? what the be the numbers to the wheels?

I would guess someware in the ballpark of 10-12 at most.
