I have been looking as well. I saw the pauchco head pipes just the other day, but now I am looking for this style of muffler. No Idea what it sounds like or if they are available?
I like this Sharktail system, want to see it in Chrome, but Shadtree has some very bad reviews on this site. I like the look when the back cylinder header joins the front at an acute angle vs almost a 90 degree. This looks to me as if it would help the flow rather than impede it.
I really want to hear it as well. This system does not have heat shields, I don't know if that is an issue.
