No its not the dual pipe exhaust it is part number RDL62900P. I used it for the first time l yesterday and noticed a big difference in power. From the teal head mach 427 with the stock losi sport pipe to this new pipe It was a big change. But the down side was when I bought it and installed it I crank the car it would run for a second and then stall out when i hit the gas. Well come to find out It was clogged at the vent hose going to the fuel tank. It was like cardboard looking stuff couldn't tell wheat it was.
