Unlock the true performance of your 2016-2022 BMW 740i or 740Li with our GCA Performance Downpipe, engineered specifically for the G11 and G12 chassis equipped with the 3.0L Turbocharged B58 engine. By replacing the restrictive factory downpipe, this performance upgrade significantly improves exhaust flow, allowing your engine to breathe more efficiently for increased horsepower, quicker turbo spool, and sharper throttle response.
Designed in-house under the GCA Performance line, this high-flow downpipe reduces back pressure to help maximize the performance potential of the B58 engine. Whether you're pairing it with an ECU tune or simply looking for a more responsive driving experience, you'll notice stronger mid-range acceleration, improved turbo efficiency, and a deeper, more aggressive exhaust tone.
Constructed from high-quality T304 stainless steel, this downpipe features smooth mandrel bends, precision TIG welds, and CNC-machined flanges to ensure outstanding durability, corrosion resistance, and OEM-quality direct bolt-on fitment with no permanent modifications required.
