Downpipe for BMW 640i G32, 740i 745 G11 G12, 840i G14 G15 B58 (2019-2024)

The downpipe is a crucial component for tuning turbocharged vehicles. Its installation enhances exhaust flow, resulting in improved performance, quicker turbo response, and reduced turbo lag. This upgrade increases power and torque, particularly in the low to mid-range RPMs, while also providing a sportier exhaust note and optimizing the turbocharging system's functionality.

This downpipe is constructed from high-grade stainless steel SS304, featuring a wall thickness of 1.5 mm for exceptional durability and resistance to extreme temperatures and corrosion. CNC-cut flanges with a thickness of 10 mm ensure precise fitment with the turbocharger and exhaust system, while TIG welding enhances structural integrity and provides a clean finish.

The design is restriction-free throughout its length, allowing for maximum exhaust gas flow.
