Products description
DTH REAPER V4 exhaust system, with ECE approval
The REAPER V4 flap exhaust system perfectly complements the sporty character of your car. Depending on your driving profile, you can open and close the system's flaps, allowing your vehicle to function as a practical everyday car, while also providing thrilling performance and a goosebump-inducing sound at the push of a button.
All components of the exhaust system are handmade, TIG-welded, and formed to meet the highest quality standards.
With the patented DTH double flap technology, your car remains quiet and suitable for long-distance driving when the flap is closed.
Upgrade
We offer a performance package for all GEN 3 2.0 TSI engines with TÜV approval, consisting of:
Control:
Since the standard flap control does not meet the legal limit requirements, we retrofit a CAN-bus controlled flap system. We check into the CAN module in the footwell using a special adapter, accessing signals such as speed, load, and driving profile, and control the flaps according to legal requirements.
How and when the flap opens:
We develop the flap control individually for each vehicle to ensure compliance with legal limits and regulations while allowing maximum sound and performance at the push of a button and driving mode selection.
The exhaust flaps remain closed when stationary to comply with legal regulations. In ECO and Comfort modes, the flaps open at 4000rpm, enabling discreet and comfortably quiet driving even at high speeds on the highway. In RACE/SPORT mode, the flaps only close within legal limits when stationary and between the 3rd and 7th gears from 20-80km/h. In 2nd gear, the flap is open (not a measurement range) and outside 20-80km/h the flaps are open. Highway measurements have shown a reduction in exhaust backpressure of over 100mbar.
Delivery Contents:
- REAPER V4 exhaust system, registration-free with ECE approval
- CAN control for flap operation
- Adapter to standard downpipe or size of choice 63mm - 89mm
- Mounting material for the system
- ECE type approval
Why DTH?
The market is full of different suppliers and exhaust systems from various manufacturers. What sets us apart?
We have been manufacturing exhaust systems in-house since 2009, and when we say complete, we mean it.
Muffler and Material:
Each DTH system's muffler is rolled from stainless steel, embossed with the distinctive stars, and then longitudinally welded. The internals of the mufflers face the greatest environmental impact; burning 1 liter of fuel produces approximately 1 liter of acidic water that attacks and corrodes the muffler's internal components. While V2A steel is water-resistant, it is not acid-resistant. Therefore, we are one of the few manufacturers who also make our perforated pipes from V4A steel.
Sound:
In combination with the muffler material, we use a special damping material resistant up to 1100 degrees Celsius, generating a unique sound in conjunction with the muffler construction.

Processing:
DTH systems are 100% TIG-welded. This cleanest and finest welding process involves a hand-guided TIG torch with a tungsten needle melting the material, protected from oxygen by technical gas. Additional material is manually added to create a weld seam that permanently connects pipes, flaps, and dampers. However, this process has a downside; the inside of the welded pipes lacks a protective gas atmosphere, causing the glowing seam to oxidize and potentially rust over time, weakening the seam's durability. To counter this, we seal the systems with special silicone plugs and fill them with argon, creating a protective gas atmosphere inside as well. This process, known as forming, ensures rust-free, stable weld seams that last a lifetime.
System:
We develop our exhaust systems on our in-house all-wheel performance test bench as part of a performance package. Typically, the systems can be complemented with a higher throughput downpipe/thermal insulation and a modified intake for a complete performance package. This is rounded off with custom programming/tuning on the test bench. We do not develop downpipes/exhaust systems as standalone components but ensure that legal requirements are met in combination with downpipe/intake/performance enhancement, allowing the registration of all components as a unit. The systems undergo extensive testing on the test bench and in emission labs for TÜV approval.
