450 (March 2024) Faux exhaust conundrum
So the 450 has a faux left exhaust, there's a few conversion kits from aftermarket (four figures, cost is mostly propped up due to the rear diffuser kit), there's full titanium exhaust replacement from the likes of Akrapovic (likely priced at five figures), and there's the OEM (AMG) conversion kits too. What would you consider a reasonable option in achieving a proper exhaust solution without dropping too much dosh?

I recently put on an aftermarket valved exhaust with the AMG functional lower valence. I kept the stock down pipe to save on complications. The stock down pipe seems very restrictive compared to the aftermarket one (300 cell cat) and I'm sure it limits how loud it gets.
Anyway, the take away is that it isn't very loud with the values fully open which I assume is equivalent to "straight pipes". I don't think I'll ever have a reason to close them. And yes, it sounds much better, not annoying or obnoxious, but sporty.

the issue with the 450 pipe facing downwards is that the noise gets into the cabin sounding like a chopper hovering. So muffler sound voices off the ground back into car.
