It was noticeable for sure but I never really pushed it with stock exhaust, I cant risk my license speeding in the street as I need it for work and only had it in the track with the Stillen. But I noticed the exhaust and then the next week I did the intake and noticed that too. Granted it isn't like adding turbos or supercharger. Main thing for me was the Oem had a resonance that echoed through the cab and sounded like it came from under the car, you could almost feel a slight buzz in the pedal at around 2700-2800 and the Stillen eliminated that completely.
