2TExc – The ultimate 2-stroke app for expansion chambers, exhaust design, port timing, intake resonance, gear ratios, and engine tuning. Optimize every aspect of your 2T engine, from mopeds to motorcycles, go-karts, and race engines.
🔧 Key Features:
1. Exhaust Calculator – Calculate full expansion chamber geometry: pipe lengths, diameters, diffuser and reflector cone angles, 1-stage and 3-stage designs. Tune exhaust waves and resonance precisely.
2. Cone Designer – Design and build all angled elements of the exhaust: reflector cones, diffuser cones, and headers.
3. Reverse Exhaust Calculator – Reverse engineer your exhaust system from geometry to resonance RPM, chamber volume, angles, and ratios. Verify designs and optimize performance.
4. Exhaust Gas Speed Calculator: Find out the exact speed of the exhaust pulse waves via proven gas equations and varying temperatures.
5. Port Timing Calculator – Calculate exact exhaust, transfer, boost, and intake timings to shape your powerband, torque curve, and peak RPM.
6. Intake Resonances Calculator – Optimize airflow and cylinder filling; match intake pulses with exhaust harmonics for peak efficiency and calculate the optimal boost bottle for your engine.
7. Gear Ratio Calculator – Determine ideal transmission steps for smooth RPM transitions and desired speed or top-end performance.
Multi-language support (English & German)
Clean, intuitive interface with instant results – no ads or distractions
100% offline functionality
🛠️ Why 2TExc?
Based on proven 2-stroke formulas and real-world results
Covers full tuning workflow: exhaust (standard & reverse), cone design, port timing, intake, gear ratios, and engine setup
Perfect for tuners, racers, mechanics, and enthusiasts seeking max performance and reliability
Download 2TExc now – and tune your 2-stroke like a pro!}
