Lightened section 3 that's near stock quiet?

[___LUNK]

Hello, my local autox site has a strict sound limit of 87dB at 75ft, so I've been running the heavy stock muffler, still got warned I blew 86dB on a cloudy day recently..

Has anybody done a lighter exhaust setup that doesn't increase sound by much? Lime rock park legal would be a good starting point.

Don't really care about keeping it looking stock, so single exits, downturns, Laguna pipe designs are all on the table.

Damn...that's low. I think you also need to look at sections 1 and 2.

I need to solve a similar issue in case I go to a track with noise limits. In for ideas.

Hmmm. I think this comes down to Section 4.

Go Dinan and turn it down.

Or Up.
