Managing exhaust noise limits - teased from Japfest thread
Japfest thread had some interesting discussions on exhaust noise at circuits, I wanted to create a more focussed thread. I have a lot of events coming up and I want to tailor my exhaust emission for each venue.

Jez, any chance you can tell me where you got this and for how much?

any ideas
Tone, what setup is you have with 3 silencers in there?
I've got a custom (APT cut and shunt :)) S14 downpipe into very cheap (it split on the welds after 48 hours!) S14 decat silencer which has been spliced into an S13 Nur Spec back system.
Ideally I would like to have something I can change easily. Looked at these options;
Apexi Exhaust Control Valve

But it kills power too much.
SUPERTRAPP Clamp On Disc

Again this could potentiall kill power too much
If I had 2/3 silencers I could swap into the decat space, each giving me 96/98/100db's that would be ideal.
