The Valvetronic Designs Equal-Length Valved Cat-Back Exhaust System solves this problem, unlocking the hidden character of the S55 while preserving the excitement and volume owners crave.\u003c\/p\u003e\u003cp\u003eThis system combines a 2.75-inch equal-length mid-section with an H-pipe and a 3.5-inch axle-back, delivering a smoother, richer tone across the rev range. With valves open, exhaust gases exit freely through the passenger-side tips for maximum presence. With valves closed, gases are routed through our quad-chamber muffler and driver-side tips, offering a quieter, more refined sound—perfect for daily driving.\u003c\/p\u003e\u003cp\u003eDirect bolt-on fitment means installation is seamless, mounting to factory points without permanent modifications.\u003c\/p\u003e\u003cp\u003eWhy It Works\u003c\/p\u003e\u003cp\u003eEqual-Length Mid-Section: Balances exhaust pulses for a smoother, more pleasant tone without sacrificing aggression.\u003c\/p\u003e\u003cp\u003eH-Pipe Integration: Improves exhaust scavenging for a fuller, richer sound.\u003c\/p\u003e\u003cp\u003eDual Sound Modes: Enjoy raw, motorsport tone (open) or comfortable refinement (closed).\u003c\/p\u003e\u003cp\u003eSound \u0026amp; Control\u003c\/p\u003e\u003cp\u003eValves Open: Aggressive, free-flowing tone with improved top-end character.\u003c\/p\u003e\u003cp\u003eValves Closed: Stock-like volume and tone for discreet driving.\u003c\/p\u003e\u003cp\u003eElectronic Valve Control: Includes remote controller; OEM valve integration optional.\u003c\/p\u003e\u003cp\u003eConstruction \u0026amp; Options\u003c\/p\u003e\u003cp\u003eMaterials: T304 stainless steel or Grade 5 titanium.\u003c\/p\u003e\u003cp\u003eWeight Savings: –20.9 lb (Stainless) \/ –47.3 lb (Titanium) compared to OEM.\u003c\/p\u003e\u003cp\u003eCraftsmanship: Precision TIG welds, fully mandrel-bent tubing.\u003c\/p\u003e\u003cp\u003eTips: Premium tips available in multiple finishes to match your style.\u003c\/p\u003e\u003cp\u003eFitment\u003c\/p\u003e\u003cp\u003e2018+ BMW F87 M2 Competition\u003c\/p\u003e\u003cp\u003e2020 BMW M2 CS\u003c\/p\u003e\u003cp\u003eInstallation Notes\u003c\/p\u003e\u003cp\u003eDirect bolt-on installation to OEM mounting points.\u003c\/p\u003e\u003cp\u003e100% reversible—return to stock at any time.\u003c\/p\u003e\u003cp\u003eNote for S55 Owners: On race or free-flow downpipes, “2k rpm rasp” may be present during low-rpm shifts.
