I just got a Megan 4-2-1 header which I'm hoping to install on friday. My question is about the O2 sensor. On the stock sensor its in the front at the top of the header, but with the Megan header the sensor goes in at the bottom right before the CAT. I was wondering if the O2 wire is long enough to just re-route it or if I'll have to splice it. I had to splice it on my old civic which sucked, I really hope I can re-route it!!!!!
