Look for ek4 vtir exhaust systems.
Itll fit better. Some b18c systems differ in length. (ie AUDM cat vs JDM cat)
b16a setups are pretty much the same throughout the range. And im pretty sure all B series vtec heads share the same exhaust bolt pattern at the manifold.
Street low end and mid end system its better to get a 2.25" system (2.25" collector - cat - catback)
Or a 2.5" collector - 2.25" cat - catback.
For more peak power go 2.5" all the way. Delete the cat and youll move the powerband closer to redline. Its up to personal preference.
I had a b18c2 with 2.5" straight through exhaust, and was very sluggish on the lowend. I think for a b18c the best setup is a tri-y headers 2.5" cat and catback.
As for intake. Short ram will most probably make you lose power than gain, as heat in the engine bay rises, so does your intake temperatures.
Always opt for CAI, cold air intake. Though the only con about it, is that with a lowered car, you have to be careful not to drive over a puddle.
Performance gains however CAI>SRI.
Good brands are all your branded ones lol.
Or you can go JDM 4-1 which is OEM honda.
Just becareful though, most exhausts will do pretty much the same thing on a stock motor. Only difference is quality and weight.
Cold air intake a fujita or injen system is probably the top 2.
And again, if youre b18c has the b18c head (ie, no secondary runners like the b18c2) youll have to look at the ek4 intakes.
Both the b18c and b16a intake manifold sit the same. The bends however are different. As dc2r's came with ABS units and the intake is designed to go around it.
Hope it helped, search around the forums too. Theres HEAPS of useful information, and also look at the traders section, ask em a few questions, they might be able to help you out in parts choices.
