Still haven't answered my question re: HP gains between exhausts. If it's just a look/sound/feel issue, I'm not overly concerned. If you get an additional 20 hp over the factory nismo exhaust, that's a different story (hyperbole but you know what I mean).

I think most of the HP claims are close to the same, but they can all put whatever they want. Just looking at all the exhaust FI has the least amount of bends, straighter should equal better flow.
