Featuring 2.5" mandrel-bent stainless steel piping, the system improves exhaust flow and passes through a single straight-through muffler before exiting via a bold quad-split rear setup. It’s finished with 3.5" black-coated, double-wall, angle-cut tips with a folded edge—offering a stealthy, performance-focused look.
 
Tuned to produce M.Flow’s signature exhaust note, this system delivers an aggressive exterior sound with a moderate interior tone. Please verify local noise regulations before installation.
 
Built to replace all exhaust components from the catalytic converter back, this cat-back system offers both performance and reliability. With precision robotic CNC manufacturing and advanced 3D scanning, it’s designed for a perfect, direct-fit installation—no modifications needed.
