🔧 Performance & Engineering

• Material Options:
  • T304 Stainless Steel — Durable, corrosion-resistant, 26 lbs lighter than stock

• Precision TIG Welding: Every weld is hand-finished to withstand sustained high exhaust temperatures and increased boost levels
• 89mm / 3.5" Diameter: Large-bore design for maximum exhaust flow and improved throttle response
• 100% Reversible: Return to stock configuration at any time — no permanent modifications required

🔊 Sound & Tone

• Deeper, More Aggressive Exhaust Note: Replaces the muffled factory tone with a raw, high-performance sound that matches the M3/M4's character
• No Drone Design: Internal resonator technology eliminates cabin vibration and drone during highway cruising
• Optional Valvetronic Control: Electronically or vacuum-controlled valves let you switch between:
  • Valves Closed: Refined OEM-plus tone — ideal for daily driving and early morning starts
  • Valves Open: Full straight-pipe aggression with pops and burbles on downshift
