Hey,
Ive been looking around for headers for my 2.5 and the only one i have found is the stillen header, but it is illegal for daily driving so i was wondering if anyone has found headers for a 2.5 that is daily driving acceptable.
The stillen headers may be illegal but they come with a black box to trick your cpu saying the O2 sensors still work so you will still pass inspection even though there will be no cat but also nismoparts.com has a header on the website that has a cat with it so it may be legal
