A friend of mine blew up his SOHC motor out of his Del Sol.. He sort just gave me the motor because I helped him with his swap.. I was wondering on the SOHC header with fit a 00 hatchback DX? Will I have to use a Catalytic Cat Converter or can I just use a Civic SI mid pipe.. Here are the parts list that I will be using.. Please let me know if they will fit the car..
1. SOHC Del Sol header
2. 00 Civic SI Mid pipe
3. Stock LS muffler

These are the parts I have right now.. Please let me know if I will need any other parts for this project..

Will I need a Catalytic Cat Converter?

 

you need the cat or you are going to throw a cel. the cat on the hb should be on the man. therefore you are gonna have to get a mil eliminator or extend the wires on #2 o2 sensor
