'02 Maxima w/ VQ35 exhaust upgrade or not?
I have recently purchased this car with less than 35,000 original miles. The SES light came on indicating rear O2 sensors in need of replacement. Had it fixed by non dealer, must go to dealer to have ECM flashed. For the long haul, is it more economical for me to install an upgraded exhaust system (headers/cat back) with the thought of more O2's and cats going bad? Is there a set up out there that would allow me to pass emissions?
