ed Posted May 26, 2004 Share Posted May 26, 2004 I think it's something like 2/3 the RPM's @ factory peak power. Or it might've been 3/4? Link to comment https://www.sau.com.au/forums/topic/41872-db-on-exhausts-limit/#findComment-858211 Share on other sites More sharing options...
Amaru Posted May 26, 2004 Share Posted May 26, 2004 For a gtst its officially meant to be 92db at 4900rpm from what I read last, but most places will just say 90db at 3500rpm.

ed Posted May 26, 2004 Share Posted May 26, 2004 I don't think there is a specific limit on individual makes/models.
