I have for sale a pair of Doug Thorley headers for the 3.3L non supercharged that are brand new. My Xterra got totaled and I no longer have any use for them. I am asking $525 OBO. These headers come with brand new mounting studs and bolts, crush gaskets, exhaust manifold gaskets, and CEL eliminators. All of these parts were purchased new from 4x4parts.com. I have receipts if anyone is interested in seeing them.
