Why do some cars sound like guns?
On a carbureted car the fuel jets will sometimes get clogged, casing a lean fuel mixture and this will cause a backfire (gun shot sounds from a tailpipe).
Why does my car sound like a tractor when I accelerate?
When your smooth-running car or truck suddenly sounds like an angry tractor, chances are good that something within the exhaust system is to blame. The problem could be a broken exhaust manifold, or it could be farther downstream in the exhaust system’s pipes and its connection to the muffler.
Why do v8 Supercars backfire?
Supercars backfire as a result of unburnt fuel exiting the engine through the exhaust system, where it then ignites and leaves the exhaust at high speed. This sometimes results in a visible flame leaving the exhaust, and is most often accompanied by a loud bang.
Is car backfire legal?
Exhaust modifications are illegal only if noise emitted is over 95 decibels. Keep in mind California smog laws or other legislation may still make your custom exhaust modifications illegal. All vehicle exhaust systems must have mufflers.
Are burble tunes illegal?
No they’re not illegal. Ford has been very public about the sport mode pops and burbles so it’s not something hidden. The EPA (and their counterparts) have tested the car in all its modes.
Why does my car roars when I accelerate?

Why do Lamborghinis pop?
Nothing about the feeling of driving a Lamborghini is accidental. According to Maurizio Reggiani, the marque’s chief technical officer, the sensation springs directly from the noise of those 12 screaming cylinders.
Why do high performance cars pop?
When an engine is running rich, it has too much fuel and too little air, which slows down the combustion process. When combustion doesn’t happen in a timely manner, the exhaust valve opens while the air-fuel mixture is still igniting, causing this explosion to “spill” out of the cylinder, making a loud popping noise.
Why do turbo cars pop?
Generally speaking, turbocharged cars can also create these sounds. The popping noises occur when ignition is retarded and unburnt fuel is sent into the exhaust system, where it combusts.
