BMW N54 Downpipes

N54 Downpipes

The Down Pipe is one of the easiest ways to unlock restricted horsepower from your turbo engine. It has been designed to allow maximum flow exiting the exhaust side of the turbo.

Features:

The Down Pipe has an enlarged pipe diameter of 3″ in order to allow gasses leaving the turbo to flow at a more rapid rate than the restrictive OEM downpipe. This improved exhaust flow will result in more horsepower and torque by allowing the turbo to spool quicker and stronger. This also allows the turbo to work more efficiently with full boost being achieved lower in the RPM curve than before.
Made from high-quality stainless steel to resist corrosion and mandrel bent to ensure a smooth flowing surface, the Down Pipe will bolt directly to the OEM turbo using existing hardware for a factory-like fit. The integrated flex section ensures that under normal engine movement, the downpipe will remain flexible to withstand such changes. The downpipe incorporates bungs for existing OEM sensors to retain proper engine management.
