Hey i am looking at getting exhaust for my rx-8 and was wondering what sounds the best. I was considering getting the HKS legamax but didnt know if it would fit on a turbo application if I decided to get a turbo later on.

 

Turbo doesn't affect the fitment of the exhaust, unless it is a custom built kit.

But try a search, there are a ton of threads on here about exhausts and intakes and whatnot. And asking what sounds the best is all about personal preference, so not everyone would give you the same answer.
