Not mentioned much on this site are the Specialty Spares pipes. I love my long slash cuts. They look similar to stock but have a really nice, loud, throaty sound. When I got them, I did get to compare with the Triumph Off Roads and the SS pipes were louder and sounded much better. They are not too loud. I actually thought they were at first (factory conditioning), but now think they're perfect. They mount on the factory mounts and come with carb re-jet kit for the TAs and BAs.
