Well the exhaust arrived last week & was fitted last Friday, it was a pretty good fit without much modding needed to fit. The original exhaust bolts were a bit of a bugger to remove and getting to the plug for the Oxygen sensor was a bit of a faff. The system as a whole is a lot lighter than the stock system (not that weight saving will make much difference), I've left the baffle in for now as I live in a small street & sometimes have to leave early for work. Even with the baffle in it's got a nice throaty note to it, I opted for the 350mm silencer rather than the 450mm and I think it suits the bike.
I'd recommend this system as a replacement to the stock if your stock system has seen better days, Delkevic provide the clamps etc with the exhaust (all stainless steel) however they don't provide replacement bolts to both the downpipes to the engine. Luckily a few spares were to hand to replace the one which had to be hacked off, in hindsight I'd have ordered a new set of these bolts but it's done now & I can always replace them at a later date if needed.
A shout out to Chris at Delkevic, very helpful chap & they threw in enough stickers to stickerbomb my fridge with.
