installed header and downpipe
 

Well today I was board as hell after work and decided to install my header and down pipe on my si hatch. It took about 2 hour for a that. There wasnt a real problem at all untill we had to pull the header and o2 sensors out. had to unplug the sensors then remove the cat and pulled out the 02 sensors. Now the only thing I need is a cat back exhaust then Im done with the exhaust.

So far I have a CAI, Header, Cat delete, short throw shifter, Shift knob and Harnesses. Cant wait to see how much HP i get after the cat back is installed.
