Need help choosing best size exhaust for a pepped up g16a, 2"...2 1/4"...2 1/2"?

Won't go into too much detail but simple info that might help, around 10.5 compression, big cam, 180 Holley (32/36), snorkel with hiflo air filter and extractors / no cat

I want a size with a nice note an so you can here the cam its got in it as well but not overly loud.

Cheers

2" will be plenty.
