I believe it did some dyno time too? The H2 is non-re-packable - which is why I don’t sell it any more. The two chambers (one at each end) are open to the hot exhaust gases, so they’ll show serious heat-staining - as does any exhaust sitting on a dyno.
Good luck with the sale
I have the same silencer as this one too…
Also has only done one trackday and several dyno sessions.
Even a few road miles too !
In comparison mine still looks nearly new tho which is why I made my comment.
I can only summise that mine has remained relatively cool cos I run quite rich mixtures…
Oh and I drive slowly
