It also includes a detailed 3D engine animation and driving simulation elements.

Highlights
  • Real-time synthesized exhaust sounds
  • Adjustable muffler settings
  • Diverse engine presets
  • Pop, bang, and flame effects
  • Living 3D engine animation
  • Driving feel simulation
  • Tunnel reverb mode

Exhaust Note is not an app that plays back engine recordings. For piston engines, it synthesizes the sound from scratch, every moment, from the firing order created by cylinder layout and crankpin phasing. Why a crossplane V8 rumbles, why a flatplane screams, why a V12 idle throbs — it all comes from the physics of firing intervals. This app computes that physics in real time. ■ Real-time synthesized exhaust - Zero recorded samples. Crank-angle integration → per-cylinder firing → exhaust-pipe propagation, computed every sample - Distinct primary pipe, mid-pipe and muffler model for every engine - Muffler continuously adjustable from straight pipe to quiet ■ Engine collection - 22 engine and motor presets: inline-3 through V12, two-, three- and four-rotor engines, a 300 kW electric motor and six motorcycle engines - 12 transmission presets: manual, sequential, dual-clutch, automatic, EV single-speed reduction and motorcycle 6-speed sequential, paired with compatible powertrains - Pick a motorcycle engine and the view becomes a motorcycle that leans into corners, with quickshifter, intake and dry-clutch sounds - Crossplane vs flatplane V8 — same eight cylinders, completely different sound - Firing order and rumble index shown as specs ■ Pop and bang + flames - Afterburn pops on throttle lift and downshifts - Flames at the 3D exhaust tips, same instant and same bank as the sound ■ Tunnel mode - Reverb that wraps the sound in wall reflections, like driving into a tunnel ■ A living 3D machine - Crankshaft, pistons and connecting rods rotate in phase with the sound - Gearbox cutaway: constantly meshed gear pairs and real synchro-sleeve movement - Observe the mechanism at 1/10 slow motion, or switch to real time for phase match ■ The feel of driving - Torque-converter launch, rev matching, manual H-pattern shifter - Haptics on rev limiter, wheelspin, shifts and ABS - Analog pedals: press position controls pedal travel ■ Electric drive - Motor, inverter, underfloor battery and fixed reduction in 3D - Original sound synthesized from motor speed, load and regeneration, without recorded samples - Simplified battery charge, energy use and regenerative braking ■ Garage, dyno and mechanism explorer - Name and save engine, transmission, boost, exhaust, body, color and assist combinations; restore the last configuration - Compare torque/power curves and estimated acceleration with shared vehicle mass and road conditions; optional matching gear ratios for combustion setups - Move through the operating cycle and choose a gear to inspect the mechanism ■ Circuit driving - Drive GT and four-door coupe models on the test circuit or an approximate 20.7 km Nürburgring Nordschleife based on public data, with forests and elevation changes - Adjustable graphics quality and saved accelerator/brake modes, pedal response, steering and assists - Local best laps are separated by circuit, engine and boost class; the three-rotor, four-rotor, electric and motorcycle powertrains currently keep records on the device only Power, acceleration and EV battery figures are estimates from simplified simulation, not production-vehicle measurements.

Verdict

The call

The clearest difference is rating: Exhaust Note at 4.7 against Cointoss 3D's 3.0. Exhaust Note also leads on update cadence (every 2 days vs every 6 weeks) and review sentiment (93% vs 75%). Cointoss 3D's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.
