67-72 & 73 & up:
454 BBC Doug Thorley 3" Tri-Y Headers Therm-Coated Like New
These are some headers that I had made but I have decided that the 3" collector size is just too big for my engines as they are built.

They were TIG welded with new 3" collectors and 3" pipe to develope them as you see for use.

These are the ONLY 3" Doug Thorleys out there ANYWHERE !!!

These were not cheap to make.

Were done to mimic installed fit an original set of DT Tri-Y's.

$750.00 OBO

I will post more pics showing the collector ends!
