I have a pair of 340 HP exhaust manifolds. Passenger side is in very nice shape. Heat riser and butterfly have been removed. The driver side however is very nice but it was broken all the way through on the output. It was tech welded back together and that’s about as far as it has gotten. Somebody should be able to breeze it up pretty nicely. Price is $550 for the pair plus shipping from Bolton, CT 06043.
