I don't think you'll be able to use any off the shelf parts unless they're made for a CTR. I have the same motor with the stock manifold. I just bought a Mugen TL CTR catback exhaust and hope it bolts up if I use a 99-00 Civic Si cat. Otherwise, I believe you can buy any EK midpipe and mate it up with a hatchback rear section (ie. T1R midpipe with T1R/Spoon rear section).

 

I recommend magnaflow cat-back system. It's fully stainless, straigth through design, quiet, & life-time warranty.
