Most people get an exhaust for the look and sound, not the performance. While some say it's a performance mod - by itself it contributes almost nothing.
I don't think you can compare exhaust vs NO2 on a close to stock 4cyl NA engine. Buy them for different reasons entirely.
Since you used to squeeze, I'm sure you've factored in the additional costs of fillin' the bottle and potential decrease in engine life.
