I will go for this if the Tomei titanium system falls through (and it seems like that is likely now).
Are the satin black tips done by you, or through CP-E?
Those are EXACTLY what I want, in TWIN tip, with a resonator.
When you say "resonator delete" do you mean the front type of resonator, or CP-E's rear, 'Helmholtz' (what they call "Stealth Pipe") resonator??
