Unleash the full potential of your S55-powered BMW with the CTS Turbo 3” Stainless Steel Downpipes, engineered for maximum flow, sound, and performance. Designed for the F80 M3, F82/F83 M4, and F87 M2 Competition, these high-flow downpipes are the first step in our modular exhaust system and a must-have for any enthusiast looking to make serious power gains.

💨 Maximum Flow = Maximum Performance

Crafted from durable 304-grade stainless steel, our downpipes feature large 3” piping that significantly reduces backpressure. This results in:

• ⚡ Faster turbo spool

Using 3D scanning and CAD-based flow simulation, CTS Turbo has optimized the design to ensure seamless integration with both OEM and aftermarket mid-pipes, including the upcoming CTS mid-pipe system.

✅ Key Features:

• 📏 3” mandrel-bent piping for maximum exhaust flow

• 🔩 Laser-cut stainless steel flanges for precision fitment

• 🧪 O2 sensor bungs in factory locations

• 💻 CAD-designed and flow-optimized using advanced simulation software

• ⚙️ Perfect fitment with stock or CTS mid-pipes

• 🎵 Aggressive, sporty exhaust note—makes the S55 engine come alive

• 🛠️ Direct bolt-on installation with no modifications required

• 🔥 Built from food-grade T304 stainless steel for long-term reliability

📦 Fitment:

⚠️ Note: Stage 2 tuning (e.g., Bootmod3) is required to prevent the Check Engine Light (CEL) due to increased flow from the high-performance cats.
