[DeTomaso] headers

Dear Rich,

              I don't know that there is a consensus.   IIRC, the Euro GTS
headers-exhaust were considered the best although they lost a reported 50
hp.  The Hall Big Bores have a smallish collector and lose more hp.  I am
also aware of one cognoscente that finds the BB exhaust note unpleasant.
Then....came the Wilkinson headers.  Initially, they were reported to look
good, sound good and have the lowest hp loss.  For a while, they were the
ticket.   Then scattered reports of poor durability due to poor construction
were filed on Pantera message boards.

              I have a '74 Pantera.  The euro GTS headers hit the left
engine mount on installation and were" fixed" in 1990 by the mechanic who
installed them with a BFH.  Years later I discovered that they *still* did
not completely clear the engine mount.     I also have a pair of Hall BB
headers on the other 74 Pantera.  The do not interfere with the engine
mounts .   Neither the GTS nor the HBB interfere with the gas tank shield.

             I suppose the easiest option is to buy a set of the euro GTS
headers.  The best and most expensive option would be to have a set of
headers fabricated.  Whatever manufactured headers you buy, CHECK the
fitment carefully before the final exhaust gaskets and bolts are applied.

                                     Warmest regards, Chuck Engles

Last experience with 2" GTS tri-wye pipe arrangement required serious gas
tank heat shield movement for clearance. Hall Big Bores not so much, but
they touched.
