i was on my way to work this morning and came upon an 04+ f150. had dual exhaust out the back and billet grill and push bar. green if i remember correctly....was about 7:30 am or so on rt. 309 between coopersburg and quakertown.....was wondering what exhaust you had....nice low sound, not loud at all......i was in my wifes car so you wouldn't remember seeing me.....

 

sounds like you were discribing my truck but im in CT... I Visit allentown about once a month though.
