    Northern California: Longtube header setup: OBX-R stainless w/mid pipe (no cats)

    Removing from truck and not putting back because I'm done with the CA smog nazis for now. I moved and no longer have a friendly neighborhood smog shop that doesn't care about the visual aspect.

    Here's a couple videos of how this kit sounds on my truck with the factory catback exhaust with the original factory muffler-
    (again, all of those videos are of this kit I am selling, on my truck, with the factory muffler and catback piping in place)
    If you have an aftermarket catback or muffler, it will probably sound different (probably a lot louder).

    Zero issues, had the kit on my truck for about 40k miles. I reused the factory manifold studs and gaskets on the heads, so the only hardware included is for the collector flanges and the donut gaskets at the collector.

    I will be including the set of o2 sensor extension harnesses that I used (required - not included from OBX when you buy), and the proper 2.5" stainless dynomax/walker slip fit band clamps to put the kit together and connect it to your catback.

    I ran a wideband with these, so it's missing one of the o2 bung plugs on the drivers side collector, you can either stick an old o2 sensor, find a plug, or install your own wideband o2 sensor there.

    My truck dyno'd 380rwhp and 520rwtq with these, a 6lb pulley, ported top end and a very conservative tune for 91 octane CA pump gas.

    $250 or trade for a nice lightning side-exit catback
    Shipping will be actual cost, much rather sell in person. I work in SF and live off hwy 1 on the coast near half moon bay, CA

    I am planning a trip to Portland around the 2nd week of Jan, and if you still have them maybe we can make something work?
