Race Cats, Test Pipes, and Regular Pipe.
I am driving a '97 Civic EX with a D16 and a GReddy TD04H-15G Kit. I want totally replace my exhaust with total 3" pipe from the turbine all the way back. My car is still OBD II, and I was wondering which would be better to run in place of my old catalytic converter (either a test pipe, race cat, or if I could just run regular pipe)? I would like some help on the differences between the race cat and test pipes, and if it is possible to run just regular pipe with an O2 bung.
so he can maybe beat my CRX lol.

get a straight pipe (test pipe) with a o2 simulator to take care of the rear o2..then your done with alot better flow and power.
