header has to bolt onto the block, so yes, Integra header.
Exhaust has to fit under your chassis and bend at the right spot over your rear axle, so yes, Civic exhaust.
I'd recommend an exhaust that at least matches GSR oem piping diameter.
Also, you'll likely have to do some cutting and welding to make the exhaust mate up with the catalytic converter at the right spot.

OP:
I had a 96' CX with a 97' ITR powerplant. I went to an exhaust shop, (sharps custom exhaust in Port Hope). Cost was $300 cash. I got it 2.5", and he custom bent everything, and welded in my High flow cat. The real expence was the CAT.
Your engine is a B series. A B18C1, to be exact. So for the most power, you want a B series Header, the rest could/should be custom. Sure you can get CX cat back exhaust... but why bother.
Also, don't buy a canister muffler... I've had 2 in my day, they both sounded the same (Skunk2 and Reactiv), was resinated, AND had a silencer... It was STILL way to loud. Look for a Borla or Vibrant muffler, but not canister!
Just me forcing my opinion on you.

i think you can buy a header specifically for b-series swaps but they might be pricey

You will need an Integra gsr header for Max flow.
You can just get all new exhaust system welded up, cheaper than buying a cat back for most of the cases.
You mentioned catalytic converters and test pipes. Its the same piece but catalytic converter is what you are supposed to have since it helps for emissions. There are few different catalytic converters, the OEM 3way and a high flow. The OEM spec ones will be more restrictive but will pass emissions test. The highflow cats will not. From experience I can tell you that it will not. While its brand new it may if your engine is in good condition, but after several thousand km's it will fail.
Now test pipes are illegal since its just a pipe, it does not clean the exhaust gasses. Though it creates no restrictions, the power gains going from a regular cat to a proper cat converter are minimal.
For sound, there are few things, the header will make the exhaust a little deeper, then depending on the catalytic converter. OEM spec will deaden some sound, high flows will be louder and test pipes even more loud. Moving down the pipe you have a resonator which acts as a sound deadner. If you choose to remove it or not use it, it'll be louder. For mufflers, you really just got to look on youtube and find one you like best. I had cherry bomb which was quiet, vibrant tank with dual tip outlet (looked like magnaflow) which was quite loud. Now running a vibrant canister muffler and without a silencer you can hear me a block away if I rev high. With silencer in, its actually not bad, just deeper but not loud.
Also, should look into getting full exhaust done in 2.5" diameter piping. If you wanna save some money you can get all pipes crimp style bent though it creates minor restrictions in flow it will not be noticible. If you have some $ to blow then mandrel bend is better.
That should have covered most of the questions.

It really depends on the canister. Most cars I've seen are silly loud even with silencer. Mine on the other hand isn't.
Though again, really depends on what the OP is looking for. If you want quiet but just slightly deeper, the WS2 mufflers/cstbacks are great.
Me on the other hand, I like the loud and obnoxious exhaust because I can't hear my female passangers yap and complain about things :P

YouTube - 2007 Civic Si FA5 Borla Axle-Back Exhaust Roll By
YouTube - civic si borla drive by
YouTube - Borla Rev & Takeoff
I've only been hassled once from my MegaPower Exhaust (skunk2)
Canister is just that... a canister... A cylinderical muffler. They don't muffle the sound very much. Cherry Bombz isn't terrible though, cheap too.
Borla is out there... I'd personally neer seen it on a Honda, just youtube vidz. I'm going with Cobb exhaust for my Subaru, and I have Vibrant for my CRX.

If you don't wanna be hassled, make sure you have a catalytic converter (your car can be pulled off the road and towed if cops/mto decide to do road side inspection) run a resonator and your choice of a muffler. Now from my experience most of the oval (regular shaped) mufflers tend to be quieter. As described above the round cylindrical shaped "canister" mufflers will be louder. Again watch youtube videos and copy the exhaust. Also, you looked for borla exhaust systems and didn't find any? You can just buy the muffler and have the whole exhaust system welded up with your chosen parts. Just make sure all ins/outs on all pieces match (except the muffler tip, that is for you to decide what size you want)

Unless you're going turbo, I would use 2 1/4".
I went to Sharps custom exhaust in Port Hope, paid $300 cash and got 2.5 exhaust from header to muffler with a high flow cat. I had my own header and muffler.

Best way to save money and get a nice sounding system is to find and buy all components (high flow cat, resonator, muffler) then piece it together. If you can't do the work your self, you'll have to find a shop that can weld it all up for you.
Just make sure all your components (cat, resonator, muffler and piping) are at least the same diameter as the collector on the header. Anything smaller then 2-1/4" on a stock b-series vtec is choking it imo. I'd try to get 2-3/8" or larger. The larger diameter the piping, the deeper (lower) the tone will be. Shouldn't go bigger than 2.5", unless it's turbo.
A lot of aftermarket b-series headers are 2-1/4", so beware. You can get a lot of these parts second hand in good condition for a lot less then what you'd pay brand-new. I bought my header, a jdm itr 4-1 with 2.5" collector for $100 in good condition.
The key to most good sounding exhaust systems is a good high quality resonator. Without it, it will sound like garbage.
Good luck and let us know what you end up with.
