Hyper Pipe is an exhaust system for your bike that looks awesome and makes realistic engine sounds as you cycle.
The Hyper Pipe works by easily fitting to the frame of your bike with a soundcard slid through the clamp, which gets held against the spokes of the wheel. When the wheel turns the soundcard vibrates and makes the engine sound and the exhaust pipe makes the sound louder. Great for adding street cred to any kid with a bike. Cool as ice.
