I got a quick quick question about this: Say for example, I had a 96-00 Civic DX/LX Coupe/Sedan (Which I Don't), and I wanted to do a DC Sports 4-2-1 One Piece Ceramic Header, MagnaFlow Direct Fit High Flow Cat, and MagnaFlow Cat-Back System, couldn't I just Un-Bolt the factory Manifold/Catalytic Converter, install the DC 4-2-1 Header that's made for the 96-00 EX Civic, install the MagnaFlow Direct Fit Catalytic Converter that's made for the 96-00 EX Civic, and install the MagnaFlow Cat-Back Exhaust that's made for the 96-00 EX Civic without having to do any cutting/welding to the Exhaust piping??

 

^ YEP..... only difference is the front piping. once you hit the rear muffler section righ after next to the passenger rear tire its the same. most aftermarket pipes have stock hangers also so its just unbolting everything and bolting on the new pipes.

 

Would you still have to do the Secondary O2 Sensor in the Header, or would you be fine with that setup?? Just curious...

 

you need both O2 sensors.

 

secondary O2 sensor would be after the cat.

please refer to the pictures I made at the beginning of the thread. I didn't think they were unclear.

 

Great write-up will definetly come in handy when I swap out my exhaust. Thanks for all of the pictures and taking the time to post this information.
