I'll give the answer as you know there are a lot of pipes out there and they all do the same thing so if you like brand names you will pay a lot more to get the same results-I have had many pipes I have one on my 300R right now paid $70 total mid pipe and muffler(Ebay) -there is a little fitting with these cheap set ups but that is half the fun I always but a second baffle ($6.50) to experiment with But there is a problem with any pipe on the 300 series-- the catalytic converter is in the muffler so any set up is going to be loud that's why I buy a second baffle to cut -drill -plug- experiment with the sound- i have had this system on my 300 about a month now and I'm just about done with the sound I think about 8-10 different tries loud but not ear shadering-they do add a little more power (seat of the pants dyno) and the bike rev's faster and the big benefit is you lose 10-11 lbs

Any aftermarket slip on will be louder than the stock set up. Most riders buy them for the better look or lighter weight or the louder sound or a combination of the above. I personally dont think a 268cc single cylinder engine sounds great with a loud exhaust but that's just me.
The first thing you need to decide is how much you want to spend as prices vary wildly from Chinese made to American/Japanese/English made.

This Scorpion is a little more than you want to spend but very good quality and with the dB killer fitted not much louder than stock. I had one of these on my Ninja 400 and was very pleased with it. A quality product made in England.

The CBR seems to adapt pretty well to losing the CAT and a drop in back pressure and doesn't pop and fart around overly. For optimal performance a re-flash of your ECU or fitting a fuel controller is always best course but by no means essential. Personally on a little low HP budget bike like this I wouldnt bother. Put the money into a decent slip on instead.
I wouldnt worry about MPG's either this thing is already a fuel miser and if there's any change it will be small.

Well I quit -after trying a pipe on my 300F and now the 300R I have come to the conclusion that they are all to loud -I must have tried 20 different ways of messing with the baffle over a month long period- there is a fine line to noise and to much back pressure and losing power so that's it put the stock pipe back on-even that simple task didn't go easy -Honda loves to over torque bolts the muffler clamp was seized --bolt stretched I snapped it with a hand tool-let me repeat that I snapped an 8mm bolt with a hand tool never have I seen that in 50+years of working on bikes had to drill the clamp out and use a 45mm long 8.8 flange bolt with a nut-that will never happen again-like I said if the cat is in the muffler any pipe is going to be LOUD
