Thanks, all went well considering I haven't done any exhaust replacements before, I did prep the exhaust bolts before to ensure they would come off nice and easy, they fitted easily and look much better!
Even though my fazer has low mileage and is in good condition, the orginal downpipes had some small holes in, so i'm glad to have replaced them. Only issue is the link pipe which stops the centre stand is slighty long and just misses the stopper! (Fine on the orginal downpipes) Other than that it went well!
