How do these cars sound like with custom exhausts?

Now I've got like 450k .. I had 550k before but I used them to buy standard cars because I like them.

Forget that, now I want to know how do these cars sound like with custom exhausts since the original sound is not that good.

Audi R8 4.2
Audi R8 5.2
BMW M3 E92
And the other prologue cars.

.. You know, I don't want my V8 to sound like a bus or a 4 cyl

I know what you mean, my corvette started sounding like a 4 cyl after the upgrade.

Well.. E92 sounds pretty awesome with semi-race muffler, Sport exhaust manifold and Cat remove.

Nice, I'll give it a try (E92). Thanks!
