35is exhaust

Has anyone here swapped their exhaust on a 35i/35is? Iím looking to make the sound a bit louder and the tone a bit deeper while keeping relatively stock to still pass emissions. I was looking at the eisenmann race, but it seems a bit high pitched and as far as I understand you loose the secondary cat. Would it then fail emissions for the second cat being missing?

Overall, anyone have recommendations or systems that they have on their car?
