my bike is a 2005 model and i bought an exhaust from a slightly newer model and its not the same . the newer model exhaust is what id consider a 'normal' one , but the one on mine has a pipe going back into the airbox, im guessing to reuse some of the non combusted petrol?

what i need to know is will it be okay to run it on the newer exhaust without the 'reburner thing'?

hopefully this made sense, ANY help or advise would be greatly appreciated

I would think it will be OK, the same applies to the DTRE when fitting a DEP pipe, just block off the pipe

nice one, in the end we just 'made' the back box fit on, hahah

well it passed its MOT anyways
