Motorcycle exhaust intelligence
Find the exhaust sound your bike was meant to have.
Dezybel turns your target sound, motorcycle, budget, and location into a source-backed exhaust report — before you buy the wrong setup.
Built for riders. Focused on sound, drone, dB risk, and fitment.
The problem
YouTube clips don't tell you what it will sound like on your bike.
Different phone mics, different exhausts, different engines. By the time the new pipe is bolted on, it's too late and too expensive to find out it drones, it's too loud, or it just sounds wrong.
Risk
Wrong tone
A pipe that sounds great on someone else's bike can be tinny, flat, or harsh on yours. Engine, displacement, and baffling change everything.
Risk
Highway drone
The resonance that's fine around town becomes a headache at 75 mph. Drone is the #1 regret riders report after the first long ride.
Risk
Legality & dB
Too loud and you risk tickets, failed inspections, or track-day ejection. We flag street-safe, verify-locally, risky, and track-only.
The Dezybel exhaust report
A report, not a chatbot.
Every report is the same scannable format: target sound, expected tone, dB range, drone risk, street risk, recommended setup, and the budget / balanced / premium alternatives — each with a confidence score and the sources behind it.

Questions, answered.
Is this just an AI chatbot?
No. Dezybel runs structured research against real sources and returns a fixed report format — sound, dB range, drone, legality, fitment, parts — not a freeform chat.
Where do the dB numbers come from?
From owner measurements, manufacturer figures, and community references. We give ranges with a confidence level, never fake-precise single numbers.
Will it tell me if a setup is street-legal?
We classify risk as likely street-safe, verify locally, risky, or track/off-road only — and tell you to confirm your local limits. We don't make legal guarantees.
Does it cover my motorcycle?
Dezybel is motorcycle-only at launch and works best for popular street, naked, and sport models. Coverage expands continuously.
