I own a V6 2015 Chevy Camaro (i'm only 16) and the factory exhaust tone isn't great. But what i'm looking for pitch wise is odd i want like a sports muscle if that makes sence. So what would be best?

A V-6 engine's exhaust note will always sound "ricey" and never ever sound like a muscle car with a V-8. I would leave it as is because I seriously doubt you would be happy with the sound. You need a V-8 to sound great, but at 16 years old the insurance costs would be very high. Drive carefully!
