Thanks mate, I was thinking it was a KTR but some of the ones I have seen have a band around them where the bracket attaches where as this one is fully welded.
When I took it off of the car the pipes were slightly discoloured, but I have cleaned it with scotch brite.
It sounds pretty good on a back road blast, but for cruising it is just slightly too noisy as the kids moan that it is noisy in the back.
How much should I ask for it do you think? It is in pretty good condition.
