I need new cats in my 02 gs and want to change the mid pipe, delete the resonator and get a hks muffler. I have looked a hks muffler made for a is300 because I want a single exit but does anyone know a mid pipe I could buy as a replacement for the resonators. And there is something after the headers and cat combo that has a o2 sensor coming out of it I dont know what it is and would like to replace it too any help is helpful!
