So im looking to change my stock exhaust, but need some opinions. I am currently looking at the Apexi Noir universal muffler. Ive read that I will probably need 2.5" piping for optimum performance. Is there anything else I should be aware of?

The exhaust is matte black and sort of a fart can look but sleeper at the same time.... Heres a link to what it looks like for those who havent seen it.
