I am going to get headers in the spring what do you think about the SS headers that ZZ Performance has. I was thinking I would get them with
the EGR, downpipe and high flow cat that you can get with them with a 2.5 downpipe exit (being naturally aspirated)and a magnaflow resonator
4"x18" body, 2.5" in/out.To the stock mufflers for now.
Also two new O2 sensors front and rear.
