My Suzuki s40 Boulevard sounds pretty good!

New rider here on my 2006 Suzuki s40 Boulevard. I bought this bike used and there are two things I've noticed compared to other s40's I've seen in YouTube videos: 1. I think my bike has a better sound from the exhaust! 2. My bike seems a tad faster doing 0-60. I'm thinking my tailpipe is after-market and that is what the difference is? Not sure. You tell me what you think about the sound! -Willie
