This is the RPM "Slim Twinz" Sedan Pipe. The "Slim Twinz" exhaust tip will add that extra flare of elegance that you’ve been searching for. These tips were designed to add Concours-winning looks to any electric R/C vehicle. These are NOT working exhaust tips, they are merely for appearance. The tip screws on to a 1/8" thick, mock, black, round muffler that has an offset tab for the entire system to be mounted to the body using double-sided foam tape or with a screw.
