Used but in great condition. These were purchased from a forum member some months ago. fitted to mine for a while before i've decided to go a different way with my exhaust.
These remove the secondary cats, add a slightly deeper note to your exhaust, sounded great combined with catless DP's. No drone to speak of, but obviously this is a personal thing.
Fitment does require cutting and flanging just before the back boxes.
