Quiet exhaust for the Defender?

[Dragoon]

The Defender is already pretty darn quiet, but it might be nice for some who wants to use the machine to shuttle people around or hunt with and I was wondering if anyone is using an exhaust or an adaptor that actually makes the exhaust quieter?

Following this thread, this is something I'd certainly be interested in.

It looks like Empire Industries sells an exhaust system that you can add a quiet core to.
