Always Fujitsubo or Megan Racing. Both are less than $950 - the Megan is probably $500 and both should and I emphasize the should part, be closer in sound to the factory system. They're both basically the same style as Nismo where it's closest to OEM style with one pipe and a big muffler (HKS is same style). Neither replaces the Y-pipe, so they won't be as loud as an Invidia or Stillen which replace everything behind the cats. You'd just have to extend the tips which any exhaust shop can do - you'd have to extend the tips on Nismo and HKS as well. The Invidia is noticeably louder, so if noise is a concern, make sure you understand that. It's not obnoxious, but it's quite a bit louder. I had mine customized to be quieter, and it's still pretty boomy. Anytime I leave a restaurant and the valet gets my car, I know when they get it because I hear it firing up.
Or just find a used factory exhaust, they're not that rare and they're cheap. I literally just gave mine away to a member for the cost of shipping. I considered junking it, but that felt wasteful.
