as with any new moddel it will take awhile for the aftermarket to catch up. the headers from a 04 will not work due to the new platform it's built on. but headers will always be a good addition to the motor. I would wait until proven tests are done one any aftermarket add on before you purchase it.
i remember on the old 98 4.6 2v they (mm&ff) put some hooker headers on and saw a 40+ hp gain......I can only hope that we get the same results from the 05 as well..340 hp aint so bad for 400 bucks.... :laughlitt
Yes it was ford intention for after markets to be there when the 05 hits the dealerships they want mustang owners to modd their car, so they left a lot of easy open ends for us to play with :0 Good ol' ford, done good
