CTS Turbo MQB Gen3 1.8T/2.0T and TFSI Gen2 1.8T/2.0T Turbo Muffler Delete
The OEM turbo muffler is a restrictor — it adds turbulence to the charged air to quiet harmonic noise, and it costs you flow. The CTS Turbo High-Flow Turbo Muffler Delete replaces it with a one-piece design cast from 6061 aircraft-grade aluminum, CNC machined in-house, for smoother airflow, sharper boost response, and a more characterful turbo note. Built for 1.8T and 2.0T engines running IHI turbochargers.
Installs in 30 minutes with standard hand tools and fits perfectly.
Features
- Original design, often replicated by other companies
- Eliminates the factory turbo outlet restrictor for smooth airflow
- Perfect fit, one-piece cast aluminum construction
- Designed and made in Canada
- Large viton o-ring included (you can also use the factory o-ring in addition)
