BMW Downpipes for BMW 3 Series G20 (2019+)

Clear BMW chassis

When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

The 034Motorsport Stainless Steel Racing Catalyst is purpose-built to replace the restrictive factory catalytic converter in BMW F2x/F3x B58 vehicles. With this downpipe installed, drivers can expect significant gains in horsepower and torque throughout the powerband. Additionally, turbocharger lag is reduced, throttle response is improved, and the exhaust note is enhanced for a more aggressive tone. By eliminating the primary bottleneck in the stock exhaust system, this upgrade allows owners to fully unlock the potential of their turbocharged engines.
