I have a 2005 Nissan Sentra SE-R specV...
I need my headers installed, they r made by SS autochrome.I never installed headers my self so i dont know how that goes. My only main concern is about the O2 sensors, ppl that drive specv's told me to get some kinda SIM for my SES(servic engine soon light)and i both that too...So im confused about the whole installation now. They said if i instal them wrong i will get a SES light. I need a shop that would instal them for.Please PM me for price, location of the shop?And if ya'll can do it this weekend...

Thanks in advance
