Hi can anyone tell me the legality of a bobcat exhaust, not so much noise wise, more the fact of the height of the exhaust gasses ejecting out

Have never known anyone getting pulled for it as they do not exit towards pedestrians on the footpath.

I've been using one for about 15 years - never had a problem.

does anyone supply a silencer insert for this exhaust

Amazing what a google search brings up     http://www.ebay.co.uk/itm/Dune-buggy-exhaust-stinger-insert-baffle-VW-muffler-sandrail-baja-fit-empi-3743-/171243047849

Have not got a clue why you would want one thou     Who said that   

I`m not sure anyone should ever take exhaust recommendations from Hudge
