Full Line Exhaust rear O2 simulator

Brand new, never used. Let's you run cat-less without an engine light. Only good for the rear, not the front. Includes instructions and a generic 4-wire O2 (for resistor purposes) that should work. Will work on most Honda's and other vehicle as rear O2's all operate on the same principle.
$40
ARP head stud kit for H22

Brand new, never used. Just missing 1 washer, bag says it's p/n AVW875N, which can be purchased separately.
$100
