[QUOTE="SCGallo2, post: 14909621, member: 160791"] Still running original cats, 33k miles, 680ish rwhp, 17-18psi boost, had 3 custom tunes on the car. Ran road course, auto-cross, 25 or so drag strip passes, and I drive it hard, 95% street/5% track... cats are holding up fine. Had the mid-pipe off over the winter to install a wideband O2 sensor and had the chance to inspect them. If you are worried about them collapsing and blowing your engine, install an Aeroforce Interceptor and monitor boost and AFR so you are aware if the boost spikes and it starts to go lean. My AFR is 11.0 at WOT and it seems to keep the cats cool enough. [/QUOTE]
