Unlock the full performance potential of your BMW G30 with the GCA Performance B46 Downpipe, engineered specifically for the 2018-2023 BMW 520i, 520e, 530i, and 530e equipped with the 2.0L turbocharged B46 engine.
Replacing the restrictive factory downpipe allows exhaust gases to flow more efficiently, reducing back pressure and improving turbocharger performance. The result is faster turbo spool, sharper throttle response, increased horsepower potential, and a deeper, more aggressive exhaust note.
Constructed from premium T304 stainless steel, this performance downpipe is built to withstand extreme temperatures while offering excellent durability and corrosion resistance. Precision TIG welds ensure superior strength and OEM-quality fitment for a straightforward bolt-on installation.
When paired with a proper ECU tune, this downpipe helps unlock even greater horsepower and torque while maintaining compatibility with your factory exhaust setup.
Designed under our GCA Performance line, this upgrade delivers the ideal combination of performance, sound, and long-term reliability.
We stand behind our products with a 1-Year Warranty.
