Flames out of exhaust bug on MB E350D 7.7L V8

I’ve noticed that when playing forza horizon 4 with the 2017 Mercedes-Benz E 350 D 4Matic all-terrain project E-AT with the 7.7L V8 engine swap, the flameout from the exhausts only appears just slightly off the left exhaust. Nothing from the right exhaust. This is fairly annoying and I’m wondering if it happens on all the cars that use the 7.7L V8.

Nope, it only happens on the Mercedes with the stock exhaust. That’s because it’s not really a dual exhaust, it’s a single pipe that splits at the back for aesthetics. You need to upgrade the exhaust too.

(What? It sounds legit to me.)
