Review on 🚗 Universal Turbo Sound Exhaust Muffler Pipe Whistle Car Roar Maker - HYXUAN 2pcs XL Size Aluminum Alloy (Black) by Christopher Hicks

I was impressed with their construction, they seemed very well made and not just cheaply assembled but as for the fastening mechanism I am deeply disappointed, one of them fell off whole car two days and I'm not too happy about it. Also disappointed that I couldn't hear anything while sitting in the driver's seat of my car, if anything it seemed to quiet my exhaust. I would suggest if you have $16 to spend but nothing else to save then you will get frustrated.
