Description

A resonated midpipe kit for Lexus IS models, designed for optimal exhaust efficiency and performance gains. It features a straight-through layout with an H-style piping design to equalize pressure. Constructed from TIG-welded SUS304 stainless steel, it includes a patented Megaphone piping structure for improved torque and throttle response. The modular design allows interchangeability with OEM components and APEXi's separately sold rear sections (164-KT02, 164-KT13). It is 4.85 lbs lighter than the OEM mid-pipe.
