We are the exclusive importer of DTH for the Czech Republic and Slovakia.
Top-quality homologated exhaust systems for Volkswagen Group cars. Sound without compromise: quiet on the motorway, full sound wherever the rules allow.
TÜV ECE homologation, documents straight from DTH and a homologation plate on the silencer.
With the valves closed it is still a comfortable exhaust that won't wear you down when you want comfort.
Precise stainless steel workmanship from a German manufacturer.
The exhaust is made specifically for your model, so it fits exactly where it should.
Measured exhaust back pressure reduced by more than 100 mbar.
Lower back pressure lets the engine breathe more freely. Suits both standard and tuned cars.
The patented double valve is controlled by data from the car: speed, load, drive mode and the gear engaged. Switch the drive mode and you switch the sound, even on cars that have no valved exhaust from the factory (e.g. Octavia 4 RS, Cupra Leon).
The valves only open at around 4,000 rpm. Ideal for quiet, comfortable driving, even on long journeys.
Valves open outside the measured range (20-80 km/h in 3rd-7th gear) and always in 2nd gear. Fully compliant with the law.

For use off public roads, an optional control module lets you operate the valves manually, including beyond the permitted noise limits.
We have DTH valved exhausts for the Cupra Leon, Formentor and Ateca, VW Golf GTI, Golf R and Arteon R, Škoda Octavia RS and Superb, and Audi S3 and RS3. Choose a make and click a model to open the product in our e-shop.

Ask usWondering how the exhaust will really sound? Put your headphones on and come for a ride with us through the city at night and the countryside, with the DTH exhaust as the soundtrack.
Recorded on a Cupra Leon SP VZ310 (2.0 TSI 228 kW). Only the exhaust was changed, with no changes to the OPF, catalytic converter or engine control unit.
Please note: for the video, the valves were operated with the manual controller, i.e. outside the scope of the homologation.
It sounds best live. Come and see us in Otice and we will demonstrate our Cupra Leon VZ310 with its DTH exhaust.

A legendary five-cylinder deserves a legendary sound, which it partly lost when the OPF arrived.

Everyone knows the Octavia RS: the guts of a Golf GTI in a family suit, the perfect everyday car. With DTH it keeps the face of a quiet family car, but once the valves open it gets a proper sporty edge.

DTH Reaper V4, 89 mm pipe, 4x 101 mm tips
Cupra is all about sporty cars. They offer performance and good looks, but not quite the sound to match. With a DTH exhaust the whole concept finally makes sense.

An R deserves a proper sound, whether it is the usual hatchback or the estate.

The Arteon R is essentially a far more comfortable Golf R in a very handsome sports estate body. So it deserves a proper sound too.

During its life the third-generation RS got an OPF and lost its sound completely. With DTH it keeps its quiet comfort mode, but once the valves open it gets the proper sporty edge it deserves.

The Sportline edition definitely deserves a better sound than it has from the factory. And if you are upgrading, why not go straight for the best there is?

Find the exhaust for your car or just ask us.
On video, or live on our Cupra Leon VZ310 at the workshop.
Each exhaust is made to order, specifically for your car.
Once the exhaust arrives from the factory, we will agree on a fitting date. We will fit around you if you are coming from further away.
Including connecting the valve control to the car's electronics.
The DTH exhaust has TÜV ECE homologation. You get all the necessary documents with the exhaust, directly from DTH. The required homologation plate is stamped on the silencer. DTH is a German manufacturer, where noise legislation is very strict, and the exhaust is built to meet it.
In automatic mode, the valves stay closed at normal revs in comfort/normal mode. From the cars we have done, with the valves closed they are at least as quiet as standard. As we say, it is not a compromise between sound and comfort.
Depending on the exhaust variant chosen, fitting takes between 4 and 7 hours. We will always try to accommodate you when planning the date, for example if you are travelling from far away.
Of course you can, we can supply the exhaust without you having it fitted with us. However, we strongly recommend having it fitted by us, mainly because it involves the car's electronics.
We try to capture the sound as faithfully as possible in our recordings, but sound through a microphone and headphones will never be the same experience as the exhaust in real life. We have our own Cupra Leon VZ310 at the workshop, on which we can demonstrate DTH for you.
Yes, the valves open and close so that the car meets its homologation. For example, in sport mode they close after pulling away for quiet driving in town and open automatically once the required speed is reached outside town. If you want the raw experience without the automatic mode stepping in, we have a module available for switching the valve mode manually.
We are preparing a collection of clothing and accessories with DTH graphics. For everyone who wants more than just to hear the exhaust and wants to be part of the brand. Coming soon.
