If you really don't know what to hear for then take it to someone who can atleast narrow it down for you. Front of engine noise can be anything.

car doesn't need back pressure(I run headers-X pipe and Magnapacks on my 00 GT-only sound from engine is injectors)---if it's a ticking sound-could be normal cycle of fuel injectors. You only running 5W20 oil? Oil pump set up for thinner oil for fuel savings-thicker oil will make oil pump work harder--need more info on noise. I even run Stg 2 cams and no problems on my 2000.
