The ultimate zero-compromise foundation for your S58. This curated performance bundle pairs the legendary high-flow IRL single midpipe with the IRL Plug-and-Play V2 Valve Controller. By removing the bulky factory resonators and center muffler section, this setup delivers a deep, muscular, bass-heavy rumble that completely fixes the flat factory exhaust note. With the valve controller in your hands, you can instantly override the factory software and lock the exhaust valves 100% wide open for full volume on demand, or command them closed for a drone-free, neighbor-friendly daily commute. 100% bolt-on installation, premium grade stainless steel construction, and no tuning required.
