Not trying to sound like a hater, just wondering why you'd go through the issues associated with removing the cats unless you're building a full on track car.

If I'm going to take the cats off and deal with those bolts, I'm not going to just put fancy cats back on. Our cats are already high-flow relatively speaking, HFC's aren't worth the money in my opinion. For me, it was test pipes or long tube headers. Went with the test pipes because I wanted more sound than anything. I got what I wanted and then some... a bunch of weird sounds. The CEL thing, I couldn't care less. I bought my car brand new here in California in 2011. I am exempt from emissions testing until 2017. I can just reset the ECU when the light gets annoying. The environment is a lost cause.
