HJS ECE Downpipe BMW M135i / 335i 3.0L N55B30A Euro 5 90812035

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 for BMW drivers.
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 manufacturer's warranty changed because the test is performed on a foreign part.

Technical data:
- incl. 300 cells catalyst
- incl. ECE approval
- Inlet pipe Ø 76 mm
- Outlet pipe Ø 80 mm

The advantages at a glance:
• lower exhaust temperature, so the charger and the exhaust manifold is more protected
• the turbocharger is able to lead off the exhaust gas easier, this is the reason for more power
• better torque range, because the charger can speed up faster

Note: This downpipe replaces the OEM catalyst with the OE number: 18.32.8.603.875
