Next to "Oil Threads", these "what is the BEST....." threads rank right up there with things that really annoy me.
THERE IS NO "BEST"!!!!!!!!
"Best" is a relative term. What's 'best' for you, may not be the 'best' for someone else. Everyone has different tastes and that goes for exhaust tone. It's called personal preference.
Do some searching and some research and educate yourself with what you feel is 'the best' out there. Not to mention that there are plenty of vids of almost every exhaust out there on YouTube.
Not to mention this topic has been beaten to death as much as oil.
