I have a 93 Civic EX coupe undergoing a B18C1 GSR engine swap.

(The shop doing it doesn't do exhaust work. They will just temporarily connect it to the rest of the stock Civic exhaust so I can drive it to a muffler shop.)

Currently it's just going to have the stock Integra header but beyond that, what do others use for the rest of the system? Do they get a cat and muffler and have a shop custom connect them or what integra exhaust parts (aftermarket or stock) can be used? And what is the piping diameter for Integra exhaust?
Just like to know what others have done for their hybrid swaps.

One other question, should I use the Integra ECU or just a wiring harness into stock Civic ECU? Does the stock ECU need any reprogramming, I'm guessing it would or at least need some wiring, or can it handle the job?
Any input appreciated.

TIA

if you want to use the stock p28, it will need to be chipped. im using the p72 simply because its plugNplay and is made for my motor.

the easiest thing to do is leave the exhaust piping alone, take the cat off and get the neck extended long enough to mate with the gsr exh. manifold.

I recommend the Skunk 2 Megapower cat-back for your Civic. It really sounds great, plus it looks good too. Get a hybrid cat from powercore or landspeed. You should get the 98-spec JDM ITR 4-1 header, that is nice.
