For Sale: Thorley Tri-Y header part number DTE 542Y-O
It has the provision for an 02 sensor, however it does not have EGR provisions, so it may not be legal for a CA truck.
I intalled it onto my truck and drove it approx 200 miles before the truck was totalled, so the header is in very good shape, still very clean with the exception of the heat coloration. No bends, or scratches.
$100 firm.
I am located In California city, CA
one hour from Barstow, 45 min from bakersfield, three hours from fresno, 5 hours from sac etc....
