Bulletproof Automotive : Kreissieg Exhaust Systems for the 360, 360CS, F430, and F430 Scuderia!

There will be a serial number on the muffler section of the system. With that, we can confirm the specs of your setup. That said, it's most likely sound level 5 with the valves open as that's what the vast majority of customers opt for. Valves closed is either level 1 or 2.

Images of the design of the system are on our site. Some exhaust flows through the cats whether the valves are open or closed, but there is a partial bypass pipe in place as well.

I've asked our Japan team to reach out and confirm specs. I'll update you once I have details. May take a week or two.

Absolutely, I'm always happy to assist however I can.

Per Kreissieg:
Serial #58105 was manufactured in August 2019, for Ferrari 430 Scuderia, with stainless steel tailpipe and sound level: silent mode 2, F1 mode 5.

 

Cats should still be mounted with some flow going through them which is likely how you were able to pass CA emissions, but there is a bypass pipe that goes around them as well with the valves open or closed.
