Description

The A'PEXi N1-X Evolution Extreme Mid-Pipe is engineered to enhance exhaust efficiency and performance for the 2016-2021 Lexus GS-F (USC10) with the 2UR-GSE engine. Built upon the foundation of the N1 muffler, this mid-pipe features parallel piping between the catalytic converter and the rear muffler, incorporating an H-style design to equalize pressure across both exhaust streams. This modular design allows for interchangeability with factory OEM exhaust system components, as well as the separately sold N1-X Evolution Extreme rear section. The piping diameter measures 65mm x 2 - 50mm x 4, and the system consists of 3 pieces. The mid-pipe weighs 25.90 lbs, which is 7.6 lbs lighter than the stock component. This N1-X Evolution Extreme Mid-Pipe is a direct bolt-on application, ensuring a straightforward installation process. It is designed to be compatible with the N1-X Evolution Extreme rear section, available with either titanium tips (part number 164-KT12) or stainless steel tips (part number 164AKT12).
