Will the /5 cigar mufflers bolt on to a /6 system? Assuming it's a 38mm pipe? Every picture seen looks that they are about the same length, on a short or long wheelbase, they seem to line up where the other regular shaped muffler lines up at the back tire. Insides can't be any different, with a baffle block and louvered tube to exit. Don't like the massive look of those regular /6 units. Just wondering if anyone mounted the cigars on a /6 and if the bolt holes lined up?
