CTS Turbo MK8 Golf GTI/8Y Audi A3 Turbo Muffler Delete

CTS Turbo is proud to release our high flow Turbo Muffler delete for the MK8 GTI with the new 2.0T EA888.4 engine. This is another original product brought to you by our engineers and in-house fabrication team. Our Turbo Muffler delete replaces the restrictive, power robbing OEM Turbo Muffler, which is designed to reduce turbocharger harmonic noise. We designed this product to keep the functionality of the factory crankcase breather system which was redesigned for MK8 models. While other companies try to adapt the older-style parts, we made this part to be model-specific and thus it will not cause any CEL or drive-ability issues. Our kit installs in 30 minutes with standard hand tools and fits perfectly. For those of you that want optimal power and boost response, this TMD is your answer. Features:

• Original design, often replicated by other companies
• Eliminates factory turbo outlet restrictor for smooth air flow
• Does not cause a CEL like other brands
• Made from cast aluminum and CNC machined for perfect fitment
• High-density sealing o-ring included
