Unlike traditional ECU tuning graphs that spike torque and horsepower primarily at low RPM, JBOM downpipes provide a smooth, linear power increase across the entire rev range—without requiring any ECU adjustments. By optimizing exhaust flow and reducing backpressure, these downpipes deliver a more seamless driving experience, improved throttle response, and enhanced overall vehicle performance. Perfect for enthusiasts seeking an ECU‑free exhaust upgrade, JBOM’s innovative design ensures reliable gains and effortless integration into your existing setup.
