Emissions stuff question
Ok, on the passanger side of the engine under the air box tube is another hose that appears to be going to somewhere under the egr valve. Mine are plugged offunder the air box? What is this for and will I need it for emissions?
Also, I currently have an off road H-Pipe on the car. I just got a stock H-pipe with cats and noticed that coming from the cates is a single tube connecting both cats that looks like a hose suppose to connect to it. Where does this go to?
