yup you don't know anything about a 2000 maxima. if you had a 2003, and you got headers, that's a different story...tell me, what's the gains on a 2000 maxima with cattman headers..JUST headers?

now if you were referring to headers + a Y PIPE, then you'll be getting rid of the precats.. now tell me, what do you know about a 2000 exhaust?
a y-pipe would be and IS the best mod for us 5th gens..not 5.5 gens...
