The CTS Turbo turbo muffler delete replaces the factory restrictor at the turbocharger outlet on facelift Audi models with the 2.0T engine. The factory turbo muffler reduces turbocharger noise by introducing turbulence into the charge air; this replacement part enables smoother airflow.
The product is made as a one-piece construction, designed using precise CAD tools and CNC-machined from 6061 aircraft-grade aluminium. Installation takes less than 30 minutes using standard hand tools. Remove the right intercooler hose, undo 3 bolts and replace the factory part with the new turbo connection.
It is compatible with factory or upgraded intercooler hoses and uses the original mounting hardware.
