What is the difference between a Resonated and a Non-Resonated Milltek exhaust?

A 'Resonated' Milltek exhaust is fitted with a centre silencer. This provides a refined, dark and sporty sound that is often TÜV/ECE approved and does not drone on the motorway. A 'Non-Resonated' exhaust has no centre silencer, resulting in a much more aggressive, louder and raw race sound.

What is the difference between Cat-Back and Turbo-Back?

A 'Cat-Back' system replaces the exhaust from the original catalytic converter to the rear (purely for sound and looks). A 'Turbo-Back' system replaces the entire exhaust from the turbo, including the downpipe and sport catalytic converter (or decat). The latter delivers the greatest performance gains (hp/torque) and the loudest sound.

Yes, absolutely. Wheels 'N Customs is not only an official supplier, we also have a professional workshop in Nijkerk. We offer very fast delivery from our manufacturers and take care of the complete professional installation of your Milltek, Eisenmann or Fox exhaust system.

Our Premium Exhaust Brands

Milltek Sport (United Kingdom)

Milltek is by far the most popular and desired exhaust brand in the tuning world, and with good reason! They develop systems from the very highest quality T304 aerospace-grade stainless steel. A Milltek system guarantees a noticeable performance gain, sublime fitment and the best tailpipe finishes (Carbon, Cerakote Black or Polished tips).

Resonated (With Centre Silencer): For a subtle, refined and deep sporty sound without drone on the motorway. Often supplied with ECE/TÜV approval.
Non-Resonated (Without Centre Silencer): The absolute favourite. Delivers an aggressive, loud and raw motorsport sound.
Valved (With Valves): Fully integrable with your car’s original drive modes (Sport/Race) or controllable via an app.

Eisenmann Exhaust Systems (Germany)

Eisenmann is the absolute pinnacle when it comes to traditional German “Handgemacht” quality. They became world-famous as the go-to supplier for iconic Porsches, BMW M models and AMG vehicles. Eisenmann exhausts are renowned for their phenomenal, deep resonance and distinctive, heavy roar.

Handcrafted: Every Eisenmann exhaust is completely made to measure by hand in Germany by master welders after ordering.
Unique Design: Available with exclusive tail-end styling such as the legendary 4x90mm tips or the unique Black Hexa Pipe.
Versions: Choice of the street-legal ‘Sport’ variant or the more extreme, unsilenced ‘Race’ variant.

Sound: Fox delivers a beautifully deep, growling tone without becoming annoyingly loud inside the cabin.

Explanation: Exhaust Systems & Terminology

1. Axle-Back (Rear Silencer)

The most accessible system. Here, only the rear silencer (with the tailpipe trims) is replaced. This provides a neater rear-end styling and a slight, sporty improvement in sound, without immediately paying top dollar.

2. Cat-Back System

This is the most popular upgrade! A Cat-Back (Catalyst-Back) replaces the car’s entire exhaust line from the original catalytic converter to the rear. Because the factory catalytic converter is retained, you won’t get faults. A Cat-Back delivers a huge sound upgrade, better flow and a small performance gain.

3. Turbo-Back & Downpipes

For those who want maximum power. With a Turbo-Back, the entire exhaust, including the Downpipe (front pipe at the turbo), is replaced. The original (restrictive) catalytic converter is removed or replaced by a High-Flow Sport Catalytic Converter. This results in the loudest sound, faster turbo spool-up times and the highest possible hp gains (does require remapping/software adjustment).

Frequently Asked Questions

Will my car still pass the APK inspection with a sports exhaust?

A sports exhaust from the catalytic converter back (a Cat-Back or Axle-back) such as a Resonated Milltek or Fox exhaust is in 99% of cases simply APK approved, as long as it is gas-tight and does not extremely exceed the legal noise limits. However, if you change the front catalytic converter (with a decat downpipe), the car will no longer meet the CO2/Four-gas measurement requirements of the APK. A downpipe with HJS Sport Catalytic Converter (200 cell) is generally APK-proof once the catalytic converter is up to temperature.

Is there a warranty on the exhausts and the installation?

Because we are an official supplier, you benefit from the full factory warranty on manufacturing defects or cracks in the stainless steel. Milltek, for example, even offers a lifetime warranty for the first owner! On our professional installation in Nijkerk we provide a standard 1-year warranty on sealing and mounting.

Does my car need remapping after installation?

When fitting an Axle-back or Cat-Back system, software adjustment (remapping) is absolutely not necessary. The engine management (ECU) can handle this perfectly by itself. However, if you go for a Downpipe (replacing the catalytic converter), it is necessary to rewrite the engine software (“Stage 2”) to prevent a check engine light and to unlock the extra power.
