The standard part is located on the outlet of the turbo compressor and is simply designed to reduce engine bay acoustics.

Whilst it subdues the harmonic noises generated by the turbo, it also adds in disruptive turbulence to the airflow right where you don’t want it.

By replacing the standard part with our maximum diameter Turbo Muffler Delete, you’ll replace this unwanted restriction with a smooth CFD-developed uninterrupted air path.

The result: noticeably better boost response giving a little more power and throttle reaction, all the while being able to actually hear your turbo working.
