We are selling off 3 sets of development headers. After testing we found minor flaws and decided to sell them off to people who worked with exhaust and could move an O2 sensor bung and make minor adjustments. Our records only show bung adjustment needed to allow O2 sensor to come through the heat shield, fitment was ok. These are sold as is, because we can't take them back after people have modified them.
Sport downpipes for BMW X5M (f85) and X6M (f86) 2015 on models with V8 twin turbo S63B44T2 motor. 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.Features:
- TIG welded 304 stainless steel.
- 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.
