Muffler Cutter Titanium Tail Style Applicable Outer Diameter: 32-58mm, Clamp-on Type I tried to install it on a Probox HEV, but it was different from what I imagined. I only lightly tightened the band for a temporary fit, so it's unused. There are fine scratches from new, but they are so faint that they don't show up in the photos.
