o2 sensor extensions

[VTPREDATOR]

ive done a search and havent seemed to come up with anything. Im fitting a full kpm exhaust system and what I would like to know is do I need o2 sensor extensions? I looked on ebay and there is ads stating that they are only needed on the models previous to 2012. any help?

cheers,

If yours is post 2012 then I'd say you don't need them. You only really need the LHS anyway on the pre 2012.
