The Boo Pipes is an unlockable heavyweight kart in Mario Kart: Double Dash!!. To unlock this kart, you must win gold in the Mirror Special Cup. This is the sister kart to the Piranha Pipes and it belongs to King Boo. Like the Piranha Pipes, the Boo Pipes has 2 Warp Pipes connected. The difference is that the Boo Pipes is a gray color to go better with King Boo's colors. While the Boo Pipes is a heavyweight kart due to its 5-star Weight rating, its other stats resemble those of a typical lightweight kart. It has both the highest acceleration and lowest top speed of all heavyweight karts. Although it has a 4-star Acceleration rating, the Boo Pipes accelerates slightly better than the Goo Goo Buggy, a 5-star accelerator. However, the Boo Pipes is the slowest of all 2-star Speed rated karts, tying with the Koopa Dasher and Goo Goo Buggy. The Boo Pipes is tied in weight with its sister kart, the Piranha Pipes, and the Koopa King as the heaviest kart in the game. Due to its strange ratings for a heavyweight kart, the Boo Pipes is one of four karts that have "out of the ordinary" stats for its weight class with the other three being the Green Fire, Turbo Birdo, and Barrel Train.
