Hi everyone.. Greetings from Istanbul,Turkey

I have a 2006 Mazda RX8 and I am planning on removing cat since inside of my car feels like being in a turkish hamam.. I just recently replaced all engine parts ordered from atkinsonrotary,I am still in break-in period which I am having a hard time to start my car so I have to inject oil from the top to start the engine but car runs like hell but engine runs rich fuel and catalytic converter is getting really really hot.I don't believe it's something to do with cat itself but I just want to remove that damn thing.. My question would be; since I don't live in states I have no such a federal law problem or getting caught by cop but I was wondering Am I gonna get any improvement on reducing engine temperature.. I am not sure if anyone tried that before but how would be the sound with AEM Air intake + Borla Exhaust? Have anyone tried that set up before with no CAT? Any suggestions and Any comments?? have a great weekend folks..
