Why are exhaust tones/notes different in each vehicle?

Question

I’m asking about motorcycles specifically but it goes for all vehicles. Why/How in a v-twin engine if CC’s are very close and the same manufacturer exhaust is installed on each bike the sound is different? Is this done with timing or are there other internal parts that cause this?

Depends on the set up, you could have a 1.0 car with a straight through exhaust system, it will sound loud and poor but it will be loud which is the main objective but won’t really see any gains as such.
