you would need it placed in the pipe after the header/exhaust manifold. Are you running the car OBD2 or are you using a jumper harness and OBD1 ecu?

if u wanna be legal since ur in cali then go with a magnaflow cat which is LEGAL to have IF you get the California approved cat..the universal type is better since u can have flanges welded on to ur application...if ur gonna run obd2 then get the magnaflow cat for 99-00 SI and if ur gonna run obd1 get a cat thats for the del sol b16a3..that way if u ever need to smog or bar ur car the cat will be LEGAL to have since its for that motor

you mean run it like how it was witht he sohc? cause on the sohc for the ek the cat is connected to the header half n half. do you know what i mean? or should i just run the cat like how its like on the integra and the civic coupe.? its a obd2 running on obd1 harness.

The EX is the only civic from '96 - '00 that had the cat under the car. I would not recommend trying to fab an in the manifold cat like the DX, CX, LX, and HX models are. That would be a PITA! SO YES ADD IT IN AFTER THE MANIFOLD/HEADER LIKE THE EX MODELS!

Stock B16A exhaust manifold (or B16A specific header) + '96 - '00 EX coupe cat + '96 - '00 EX coupe intermediate pipe + stock '96 - '00 hatchback axle back/muffler = 100% bolt on exhaust.

Go buy a universal one, bring it to a muffler shop, have them cut and weld it in with flanges so you can take if off when you need.
