Review on 🚗 RDEXP Silver Size M/37-48mm Aluminum Alloy Turbo Whistle Exhaust Muffler Pipe for Car Modification by Elvis Kimbro

So I watched a few YouTube videos before buying two of these for my Mercedes and it does literally nothing. It was a waste of time and money, but I was just a little curious. Don't waste money on it. I also tried this on my Genesis G90, it did nothing to produce or change any sound. The instructions that come with it don't explain much either. So if you buy it, be sure to watch a few videos before spending a lot of time on it. Much luck.
