Nice Steve, are you installing them on a 1199 or 1299?
1199. Ordered them as such on a whim last Friday night (IPA frenzy?) and they came with the appropriate Y-Pipe and the Sprint Filter.
A teeny bit conflicted on them at this point to be honest, as it's hard to see how they aren't going to be louder than I want; you can look in the outlet and see daylight coming in from the other end - they really are straight-through. Look to be an easy install; Termi and all their distributors are claiming a big improvement over the OEM flat spot with no tune required - we shall see.
