In addition to the benefit of opening up the air flow, the sound is also more aggressive sounding and for me that was what I wanted. I have no issues with the smell of fumes. Never had a problem passing emissions, since no CELs are on it. Here they won't sniff test it unless you show having thrown a CEL(s).
