    Active Autowerke mid-pipe o2 simulators e36

    Takes the place of the cats for an e36, but I've seen people use them on 24v swapped e30. Comes with o2 simulators so the check engine light is not thrown.
    I've used them on and off for maybe a year, so there's a few scratches but nothing crazy.

    Look to notice gains in lower rpm's, especially when paired with a headers and a proper cat back.

    Looking to get $550 picked up in the Bay Area.
