Unlock the full performance potential of your BMW with the German Car Accessories 2016-2019 BMW 320i / 330i / 420i / 430i B46 Downpipe. Developed under the GCA Performance lineup, this high-flow downpipe is engineered specifically for BMW F30, F31, F32, F33, and F36 models 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 faster. The result is sharper throttle response, improved mid-range acceleration, increased horsepower and torque potential, and a deeper, more aggressive exhaust note. When paired with an ECU tune, this downpipe helps unlock even greater performance from the B46 engine.
Manufactured from high-quality T304 stainless steel, this downpipe is built to withstand extreme temperatures while providing exceptional corrosion resistance and long-lasting durability. Precision TIG welds and smooth mandrel bends ensure maximum exhaust flow, superior strength, and OEM-quality fitment for a straightforward installation.
Whether you're building a daily driver or a dedicated performance vehicle, this GCA Performance downpipe is one of the best upgrades for maximizing the capabilities of your turbocharged BMW.
German Car Accessories proudly stands behind every GCA Performance product, and this downpipe is backed by a 1-Year Warranty.
