Muffler Set Kyosho Inferno MP9 TKI4 RS

The original Kyosho Nitro USA-1 set the standard for RC Monster Truck power and performance when it was released in 1990. 30 years later, the torch has passed to the newest Nitro USA-1, which outperforms the original in EVERY respect. Yes, it's that much better… and we even build it for you.
