Changed header on my race car so this is taking up space.B SERIES , Made good power for me, tri-Y to 2.5 configuration. Used for one Racing season. ZERO street driving so has very small amounts of scratches. $150 OBO Will ship but rather meet up for exchange

 

To be sure, does this eliminate the catalytic converter?

 

I have never had a cat on any of my Hondas but I don't think it will eliminate the cat. I've had a couple different headers and they were all the same length.
