Here is a pic of 6.2L headers from American Racing Headers now avail.
These are for the Raptor but we are seriously thinking this system might just fit the Super Dutys with minor modification. ARH has sets out for the 5.0 mustang and stock no tune and headers no tune picked up some great gains 30-40 hp roughly if i remember.
There should be some before and after dyno results on the Raptor some time soon I hope from ARH.
