Sorry to but am I reading that catless can in fact be tuned out completely without going EWG or polishing? I have had numerous conversations with some friends around my area about this. I was originally going catless until contacting Torqued performance and Socal and Plano Cobb. They basically said I will have boost creep and pushed catted. I was also told that if I went with a intake (which I have, no performance reasons, just wanted sound) and with a 3" exhaust I am basically set up for prime creep issues. My friend on the other hand said he had the exact opposite reaction, pushed towards catless. I am in a 2013 WRX and my friend is in a 2013 STI.
