Check this video to compare the sound of the stock exhaust vs the Lextek exhaust with, and without DB killer inside. Use headphones or good speakers for quality sound.
You can hear the difference in sound very well but the difference in volume is hard to record. For comparison, you will hear the stock exhaust while riding with helmet on up to 50km/h, lextek with DB-killer inside up to 80/100km/h and without DB-killer you will hear it all the time.
The weight saving is mentioned in the video.
