I thought it would be good info for the faq. A Prelude header will fit on the CB7 90-93 Accord. You will need to drill out the threaded holes and use nuts and bolts to connect the two pieces. Also the nuts and bolts will need to be tightened from the top side.

 

Even if someone wanted to do this, it wouldn't work for the EX models.

 

If you need a header and you happen to have a prelude ebay brand header. It can be installed on an 93 accord lx. My obx header flex pipe broke and I got a prelude header for $15. You need to extend the oxygen sensor wires. The point is it works if your in a pinch.

 

Oxygen sensor wires are not something you want to leave to chance. If at all possible, and it usually is, you want to avoid doing any type of cutting to oxygen sensor harness wires.
