Thanks for reporting back.
My rear silencer has been suffering corrosion of the outer skin for a few years now (so much so it's been an MOT advisory), though the inner skin is fine so it's still doing its job. In the absence of an OEM solution, I've been intending to fit a full stainless system, but have been holding off in the hope that something close to OEM becomes available. It sounds like this could be the answer
.
Do you happen to know how this is likely to compare (sound wise) to the "quiet" solution offered by Longlife? I'm guessing it will possibly be better.
