[QUOTE="SCGallo2, post: 14889498, member: 160791"] Yes, your factory cats are better in your application. I am still running my original cats with a good tune. I recently had the mid-pipe off to install a wideband O2 sensor and had the opportunity to get a good look at them, and they are in great shape. If I install a 10% OD lower pulley and/or mono-blade throttle body to further increase boost, I would install an off-road H or Kooks headers with green cats to handle the additional flow, but that would probably force me to replace my mufflers due to the increased noise level.
