I understand where you are coming from and it might just work.
Not sure if the timing is right but I will say this...SC430s are finally getting low enough in price that younger folks will buy them and they would be interested in high performance.
Most older folks, 50+, not so much, but some still would bite.
Anyway, I wish you luck and hope the timing is right for you!

Sorry about the slow reply. The PPE headers and custom exhaust on mine produced 307 bhp at the flywheel. It was measured on a Dynojet rolling road, the car was running on normal UK 97 RON fuel. The tester noted that it was too rich at the top end and said it would easily make 317 bhp if leaned out. I put it down to a dirty MAF sensor but it hasn't gone back to the dyno yet as it's waiting for an X pipe to be fitted first.
The exhaust configuration keeps evolving, I just have one more change to make in swapping the Y pieces for a new X pipe.
PPE headers (driver-side custom made in UK) to primary cats, to Y piece to 3 inch short pipe, to Y piece, then straight pipes back to center silencer and then side exit on each side of the silencer to quad tails. The third cat has been deleted, it did have 2 center resonators in the custom exhaust but I later removed them too when changing the round tails to larger ovals. It's not too loud and doesn't drone at any speed.

And here is the Y piece that hopefully will improve the flow and scavenging effect.

In the car, it's still quite refined until you kick it down and then it sounds like a V8 should but it's still not too loud.
The headers made only a very subtle difference to the sound but a very noticeable improvement in terms of acceleration. From listening to other SCs with exhaust modification, it's the rear silencer (muffler) that keeps a lid on the noise. The center resonators make a difference but far less. Cars without a big rear muffler and the middle resonators left in have a deeper burble sound.
Here's a clip after the center resonators were removed. I think this would only help the gains from Supercharging. Are there any more details on the package?

Is there enough room in the LS430 engine bay for long tube headers? I did have a lovely 2004 LS430 a few years back but can't remember.

That is a very nice looking ride! The wheels look good all black!
