Tachen! I bought a Bosi 90er final pot for my 176er. Now my question: “How do I not get the insulation wool completely away so that the illegal becomes, but only bring the insulation wool to the, well almost shrink?” Is there no means? Many talk about WD40? What exactly and above all does someone have experience with it? Exhaust is not yet grown, because I want to make the whole before! Hope someone knows each other out here! Thank you….
