Burbles getting LOUDER

I have the n20 engine, Ever since deleting my muffler(1st) and resonator (2nd) my car pops and bangs keep getting louder. Also starting to get abit of the rotten egg smell, could this be due to me blowing out my cat slowly? I do drive pretty aggressive (letting car rev out and pop) still have my stock downpipe and no tune
