Our new Gen2 Racing Dynamics sport downpipes for BMW X3M (f97) and BMW X4M (f98) 2019 on models. Our Gen2 Downpipes include improvements in flex joint to reduce vibration and allow alignment during installation, O2 sensor bungs for reinstallation of the OE O2 oxygen sensors, and mounting brackets to support the weight. Down-pipes by there very nature reduce restrictions of the catalytic converters allowing your turbos to breath more efficiently. This reduced restriction allows the turbos to spool up more quickly and provide a more aggressive turbo sound. Most downpipes since they no longer have catalysts may generate check engine lights. Our O2 sensors spacer is a possible solution. Features:
- Large diameter TIG welded 304 stainless steel piping throughout for maximum power.
- Direct bolt-on replacement for OEM primary catalytic converters.
- Our heat shield version protects surrounding parts, wires and hoses from rheat of the downpipes. The integral thermal insulaion reduces head radiation and passes the heat out the exhaust.
- Straight-through design allows for maximum power and sound. Less back pressure improves turbo response and improves horsepower and torque significantly.
