Totally excellent exhaust very nice quality and the sound is awesome , I left the baffle in and the sound is deep and performance is improved. Fitting took 10 mins The only tip I could give is use a small amount of jointing past on the joint from the can to the adapter no need on the other joint as the sealing ring is provided All this with next day deliver it’s a winner ( I fitted it on a 2017 SM Apache looks mint)
