How it works
A report, not a chatbot.
Every Dezybel report follows the same eight-step pipeline, so you get a consistent, scannable answer instead of a freeform guess.
Vehicle fitment
You enter year, make, model, engine, and current exhaust. We anchor every recommendation to what actually bolts onto your bike.
Sound target
You choose the character you want — deep or raspy, civil or aggressive, street-safe or track-only — so the report optimizes for your taste, not a generic 'best' list.
Source-backed research
The engine searches manufacturer pages, retailers, forums, owner reports, and dB references — never a single YouTube clip — and weighs what it finds.
Synthesis
It resolves the evidence into one recommended setup plus budget, balanced, and premium alternatives, each with its tradeoffs.
dB range
You get a loudness range with a confidence level and the reasoning behind it — ranges, never fake-precise single numbers.
Drone risk
We flag cruise-RPM resonance risk so you don't discover the drone on your first highway ride.
Legality risk
Street-safe, verify-locally, risky, or track/off-road only — clear risk language, no false legal guarantees.
Install checklist
Fitment notes, whether a tune is needed, and the steps to install it right.
