Does anyone know the best (reasonable cost) way to get more exhaust and a little louder sound from a 2021 Cayenne Base model?

most downpipes cost over 3K. And it won’t be so effective if you have the standard exhaust.

if you have the sport exhaust check Cargraphic valve control which allows you to completely open your valve all the time. One guy here with V8 GTS was considering DP after he installed that module he forgot about the DP. I believe this would be cost effective solution.

otherwise, if you not worry about warranty issue muffler delete is the cheapest best solution 👍
