Which LT Headers and X-pipe

[white88stang]

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.

I'm not sure if American Racing can be left in place when dropping the clutch.

I have read many times over that pypes long tubes are a direct copy of kooks. If that true then they are not what you want.
