355 Exhaust bypass valve refurbishment

Having had my bypass valve rattling like a machine gun I contacted an engineer friend of mine, I removed it from the car and he dismantled it and fitted new stainless steel bushes to the body machined to fit the current shaft, reassembled and refitted back in the car it is as quiet as a new one. If anyone else with a 355 has a noisey bypass valve and wants to have it repaired he is quite willing to do it for the cost of £200 a big saving on the £480 required for a new one.
His name is Matt of Format Fabrications in Horndean Hants tel number 02392571181, he will need the valve for a week.
