The whole DC Sports parts breaking thing is grossly overexaggerated internet mythology. While it is true that a tie bar or two did break or bend or something, that turned into people talking about how the entire product line is shit. It's not.

However I would say that my favorite bolt-on exhaust for Integras is the Tanabe Super Hyper Medallion. It's full stainless (i.e. the piping and the muffler unlike the A'PEXi WS which only has a stainless muffler but not pipes) but still not overly annoying in sound. That's what I would buy if I was you.
