Which long tube headers make the most power and can be left in place to service the clutch on an 2005 4.6L? I talked to Pypes and you have to remove the headers to drop the trans, plus they are Chinese made.
I though someone said the Kooks headers and X-pipe could be left in place, but can anyone confirm? What about leaks? My car is a daily driver and I don't want to deal with header leaks constantly. Thanks.
