Unlock the full performance potential of your BMW with the German Car Accessories 2016-2022 BMW 730i / 740e B46 Downpipe. Developed under the GCA Performance lineup, this high-flow downpipe is engineered specifically for the G11 and G12 BMW 730i, 730Li, 740e, and 740Le equipped with the 2.0L Turbocharged B46 Inline-4 engine.
Replacing the restrictive factory downpipe with this GCA Performance upgrade significantly improves exhaust flow, reduces back pressure, and allows the turbocharger to spool more efficiently. The result is quicker throttle response, increased horsepower and torque potential, stronger mid-range acceleration, and a deeper, sportier exhaust note that enhances the driving experience while maximizing the efficiency of the turbocharged B46 engine.
Constructed from high-quality T304 stainless steel, this performance downpipe is built to withstand high exhaust temperatures while providing outstanding corrosion resistance and long-lasting durability. Precision TIG welding and smooth mandrel bends ensure superior strength, optimal exhaust flow, and OEM-quality fitment for a straightforward installation.
Whether you're upgrading a daily-driven luxury sedan or building a more performance-oriented setup, this GCA Performance downpipe is an excellent foundation for extracting more power from your BMW.
