HJS ECE Downpipe Audi RS3 8V, TTRS 8S quattro 400 hp 90811170

Downpipes are dimensionally involved in the points of draft and performance.
They are the “link” between the exhaust probe and the exhaust system.
The catalyst developed by the HJS Tuning experts has gone through all stages of development.

Made of stainless steel and coated with the motorsport-derived calotte thermal insulation, is now available a high-tech tuning product.
The significantly reduced exhaust backpressure of the HJS tuning catalyst is not only for reduced temperatures in the turbocharger, but also for a significantly better response of the engine.

Of course, a performance and torque improvement is to be checked exactly. In addition, the metal carrier used provides even for a sonorous sound.
With the ECE approval, a booking in the vehicle documents is required, nor is the manufacturers warranty changed because the test is performed on a foreign part.

The values measured by us result in 23,5% less exhaust back pressure and depending on engine speed a power increasement of 5-19 HP.

The advantages at a glance:
• 200 cpsi tuning stainless steel catalyst
• New development! Carrier Ø of153mm
• Pipe diameter:
      OEM: Ø 55mm -> Ø 60mm
      HJS: Ø 60mm -> Ø 63,5mm
• Plug & Play
• The turbocharger is able to lead off the exhaust gases easier, this is the reason for more power
• Better torque range, because the turbocharger can speed up faster
• Lower exhaust temperatures, so the turbocharger and the exhaust manifold is more protected
• incl. ECE approval
• HJS integral isolation
