  • Exhaust Noise levels

    This is a question to those who've had the noise levels of their exhausts measured at track days. What exhaust do you have and what are the noise recording levels?

    In static noise tests @ 5000rpm my Eisenmann "road" is about 88db (factory about the same).

        Maybe mine was less then! I'm not sure how loud yours is Andrew but mine is pretty similar to stock (as you might remember from Donington). I think also with meter readings they're pretty haphazard unless it's the same meter on the same day/conditions. However it's always below 90db.

          Noise!

          Mine has Supersprint Race front pipes, no CATS, & full Supersprint race system, always 92db at 4,500rpm & 94db at 5,000rpm.

            Especially at Donington with bloody great jets flying overhead.

              Yours is quiet Chris, but my ProSpeed is only noisy under load and on start up. It's surprisingly quiet at 4750rpm

                  84db with the exdos version of the standard exhaust. clubmsv so static at 3800 I think.
