I have a puney Civic HB CX. For know I am doing all my exterior and interior work, saving the engine for the summer so I can actually learn how to do it, I have a quick questions. I love the N1 exhaust everything from the way it sounds to how it looks. I notice everyone sells it for the HB except the VX and CX I am guessing because the cat comes straight off the exhaust mani. If I get that exhaust a high flow cat and some headers I should be fine right? Thanks!?

 

You are going to need a dx/ex/si header and mayching cat. You will need to extend the 02 sensor wires. I'm not sure if you will throw a code or not since the o2 is going to be relocated further down the header.
