when I get ready to buy a pipe it will be a supertrapp.....either the ids2 or 4" race series.probably the 4" race series. from supertrapp the ids2 is $314.95 and I can get it for $240 at rocky mountain and the 4 " race series is $294.94 so I figure I can get for atleast as cheap as I can the ids2. anybody know of a place that has this pipe cheap? I'm pretty sure this comes with a header. thanks
