Review on NEW! High Performance Exhaust System Muffler For GY6 50Cc-400Cc 4 Stroke Scooters ATV Go Kart (Silver) by William Stewart

The only reason I'm giving this a 4 and not a 5 is because my buggy backfired once. Breaking a weld in a bulkhead by shooting at it 4ft from the buggy. I had to bend the exhaust pipe to get it to fit properly, but I knew some self-adjustment would be required. It has a great sound both with and without a deflector. Gives it more of an ATV or dirt bike sound. All in all I am very happy with this product and believe me after hearing it you just want to play with the gas!
