Our Luxury+ was ordered by the dealer with the following performance exhaust option and it has a nauseating drone that resonates through the cabin.
Quality performance exhaust systems usually have an aggressive exhaust note/tone but no drone - not the case here.

Wondering if anyone has downgraded and what the cost was. Our GX550 is only a few weeks old.

Catback Performance Exhaust $2270
