Whats a TB?
Check your engine mounts, if the engine moves it pulls at the flexi pipe.
Mabye not but if you dont get that sorted first then the engine will pull apart any exhaust that you try to fit. If the mounts are worn every time you accelerate and decelerate the engine moves back an forth puling at the exhaust.
From memory non turbo diesel is a lot different to the rest of the range.
