I run a similar set up except mine's chrome matches up with the standard roadster heat sheild. Sounds nice a bit like a Trident running a 3 into 1, looks good I like the shaft side with no pipe and weighs 2 kg the original system weighed 18 kg and looked like they belong on the back of a Kenworth cab. With PCV and dynoed and me being 72 kg it's a bit of a sharp stick.
Reckon the cut-down guard and the black muffler set-up looks neat. Like the fact owners just can't just go buy bits out of a catologue , they got to modify what they've got... And i'm one of the elite ' custom header-pipe ' crew
