🔥 CTS Turbo Catless Downpipes – BMW F10 M5 / F06 F12 F13 M6 & Competition Models (S63)

Upgrade your BMW’s performance and sound with the CTS Turbo Catless Downpipes, engineered for the S63 4.4L Twin-Turbo V8 found in the F10 M5 and F06/F12/F13 M6. These downpipes are designed to maximize exhaust flow, improve turbo response, and unleash the true tone of your M-car.

💨 More Flow, More Power, More Sound

By replacing the restrictive factory catalytic converters with high-performance cast T304 stainless steel downpipes, you’ll experience significant performance gains and a more aggressive sound profile.

• ✅ Free-flowing design for improved exhaust velocity

• ⚡ Faster turbo spool-up and better transient response

• 📈 Substantial horsepower and torque increases with Stage 2 tuning

• 🔊 Deeper, louder tone with enhanced crackles and shift "punch"

• 🚫 No drone when paired with the OEM exhaust system

If paired with an aftermarket exhaust, expect an even more aggressive, motorsport-inspired sound.

🏗️ Built to Perform & Last

Designed using advanced CAD modeling and real-world testing, these downpipes are built to fit perfectly and perform flawlessly:

• 🧱 Cast T304 stainless steel construction

• 🔩 TIG-welded and back-purged for superior durability

• 🧪 Direct-fit replacement for OEM catalytic converters

• 🛠️ No cutting or modifications required

📦 Vehicle Fitment:

⚠️ Note: A Stage 2 tune (e.g., Bootmod3, MHD, etc.) is required to remove the Check Engine Light (CEL) caused by catless operation.
