Laguna sound solutions for an FC?

[Rick Kirchner]

Searched back through all the old posts and didn't see anything recent. I was able to pass normal SCCA sound with nothing more than a 90 degree turnout.

Coast Fab seems to be gone. I do have a heavy Phase 9 which will take a bunch of fitting and what was once a car that met minimum weight is now nearly 50 lbs over (worthless 1175 pound "gimmie" plus spec tires).

What are people using now?

I think Pro-Fabrication took over the Coast Fab mufflers:

But you can also find similar from Burns Stainless:

Even with the muffler you can exceed the sound limit.
Make sure you have a turn-down and clock it about 7:30.
Sound booth is on the right between 5 and 6 and you'll be going full beans.

If I rig up the Phase 9 I should be good, but god is it heavy. I used it a few times many years ago and I could hear the valves ticking behind my head!

It's not just exhaust noise that can blow sound. Induction noise, gear noise, and even flapping bodywork. My son's super seven blows sound from the Weber DCOE induction noise. One competitor was called in for sound and the monitor said it sounded like a loud whine. His gearbox was near failure. Saved him a catastrophic failure.
