Thanks in advance.
1. The sound was never "good", it was always annoying. You just didn't know it or want to admit it.
2. Put a real muffler on it, even a high performance unit. Fart cannons are trash. I don't know the exact dimensions you need but your basic 2.5" inlet and outlet turbo muffler would be fairly inexpensive and much quieter under normal driving conditions.
