The CTS Turbo 3.5″ downpipe with a high-flow catalyst is designed for Mercedes-AMG vehicles with the M133 engine. The factory downpipe heavily restricts exhaust gas flow, which is particularly noticeable on modified vehicles. The larger diameter and high-flow catalyst allow smoother exhaust gas flow.
The product is also suitable for use with the standard exhaust system, providing a sportier sound without annoying droning. Stage 2 software is required to prevent the engine warning light from coming on.
