I rarely smell the excess exhaust gasses from my ART + F.I. combo. Usually, I only detect it with my windows down and I come to a complete stop. With the windows up I can't recall ever smelling it.

My previous car was an eclipse and I could smell the headers all the time, but with the Z in all honesty I rarely smell it.

Most of the time it's with the windows rolled down at a traffic light. I hope that helps.

I saw somewhere that you have the FI 12" resonated and ART pipe combo and mentioned how you liked it. Any thoughts on the smell from the ART pipes? One forum member had the FI 18" and ART pipe combo and said that he did not how it smelled. Any feedback is appreciated. I can tell that my wife is kinda sensitive to the smell. Thanks for your help on this.
