ECE/EG/TÜV conformity and performance improvement

The Milltek complete system is the ideal solution for tuning enthusiasts seeking an exhaust system that not only meets ECE/EG/TÜV requirements but also takes their turbocharged engine performance to the next level. But that's not all – these systems also deliver a distinctive sound that will delight any tuning enthusiast. With their striking, confident, and sporty design, they're not only functional but also visually appealing.

High-quality stainless steel from aircraft construction

What makes these complete systems special is the high-quality stainless steel material, which was specially adapted from aircraft construction. This makes them exceptionally robust, durable, and rust-free. Best of all, all components of this system are made of this high-quality material. It's also anti-magnetic and retains its color even with long-term use.

Optimal tuning for outstanding performance

A complete aftermarket exhaust system includes the components of an exhaust system that follow the catalytic converter. These include the front muffler, middle muffler, rear muffler, and tailpipe, depending on the engine and model year.

Milltek complete system - highest quality and driving pleasure

Milltek makes no compromises when it comes to manufacturing sport-modified systems. While the stock version serves its purpose, an aftermarket Milltek complete system offers far more. Not only do the production standards meet strict ISO criteria at the highest level, but the power delivery is also impressive. Thanks to the special design of the components, the engine can breathe freely. Typically, a Milltek complete system results in a reduction in exhaust temperature and back pressure, which leads to increased power across various engine speed ranges.

Excellent choice - Milltek complete system

While it is possible to simply install a new muffler (front silencer, mid silencer, or rear silencer) and hope for an improvement in performance and sound. This may be more cost-effective than a full system, the components will not be perfectly matched, preventing your engine from reaching its full potential. However, if you plan on really pushing the throttle, the Milltek full system is the optimal choice. It is available for a variety of vehicle models, including the Audi A3, A4, A5, Seat Leon, Seat Ibiza, Nissan GT-R, BMW 1 Series, 2 Series, 3 Series, Ford Focus, Ford Fiesta, Honda Civic, VW Golf, VW Polo, VW Polo GTI, New Mini Mk2, Mk3, Mercedes A and C Class, and Porsche Cayenne.
