The Nismo exhaust does sound deeper and a bit louder than the original pipes, but the difference is so slight that I can't tell at all when driving with the top down in traffic. On the other hand, I only have 600 miles on my car and I'm trying to follow the owners manual break-in instructions so I haven't heard what it will sound like at full throttle.
