APEXi Non-Resonated N1-X Evolution Extreme Midpipe for Lexus RC F 2015+ - 144-KT01P performance upgrade part

Designed for the 2015+ Lexus RC F, this aftermarket midpipe connects between the catalytic converter and rear muffler section, using a parallel mid-pipe layout to support efficient exhaust flow. The H-style piping design is used to help equalize pressure across both exhaust pipes while maintaining a modular layout.

SKU: APEX-144-KT01P

Built from tig-welded SUS304 stainless steel, this midpipe is matched and manufactured for select chassis and uses APEXi’s patented megaphone piping structure. The non-resonated configuration is intended to deliver a sharp, clean exhaust sound while supporting strong throttle response across the powerband.
