Our new Gen2 Racing Dynamics sport downpipes for BMW X5M (f85) and BMW X6M (f86) 2014-18 models with V8 twin turbo S63B44T2 motor. 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 will generate check engine lights. Our O2 sensors spacer is a possible solution.
- Large 3" diameter TIG welded 304 stainless steel piping throughout for maximum power.
- Direct bolt-on replacement for OEM primary catalytic converters.
- Straight-through design allows for maximum power and sound. Less back pressure improves turbo response and improves horsepower and torque significantly.
