Unlock the full performance potential of your BMW with the German Car Accessories 2019+ BMW Z4 sDrive20i / sDrive30i B48 Downpipe. Developed under the GCA Performance lineup, this high-flow downpipe is engineered specifically for the G29 BMW Z4 sDrive20i and sDrive30i equipped with the 2.0L Turbocharged B48 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 and more efficiently. The result is sharper throttle response, increased horsepower and torque potential, improved mid-range acceleration, and a deeper, more aggressive exhaust note that transforms the driving experience.
Manufactured from high-quality T304 stainless steel, this performance downpipe is designed to withstand extreme exhaust temperatures while providing excellent corrosion resistance and long-lasting durability. Precision TIG welding and smooth mandrel-bent construction ensure maximum exhaust flow, superior strength, and OEM-quality fitment for a straightforward installation.
Whether paired with an ECU tune or additional GCA Performance upgrades, this downpipe is one of the most effective modifications for unlocking the full potential of your turbocharged Z4.
German Car Accessories proudly stands behind every GCA Performance product, and this downpipe is backed by a 1-Year Warranty.
