Downpipe HJS Sport Catalyst for BMW M135i / 335i 3.0L N55B30A Euro 5-EC Approved-Part Number 90812035

Description

Downpipes intervene dimensionally in the draw and power points.
They are the "link" between the exhaust probe and the exhaust system.
The catalyst developed by HJS Tuning experts has gone through all stages of development.

Made from stainless steel and covered with a motorsport-derived heat-insulating shell, a high-tech tuning product is now available for BMW drivers.
The significantly reduced exhaust back pressure of the HJS tuning catalyst not only helps to reduce temperatures in the turbocharger, but also significantly improves engine responsiveness.

Of course, an improvement in performance and torque must be precisely verified. In addition, the metal bracket used ensures a sonorous sound.
With EC approval, an entry in the vehicle documents is required, and the manufacturer's warranty is not affected because the inspection is carried out on a foreign part.

Technical data :
– with 300 cell catalyst
– with CE approval
– Inlet pipe Ø 76 mm
– Outlet pipe Ø 80 mm

The advantages at a glance:
• lower exhaust temperature, so the compressor and exhaust manifold are better protected
• the turbocharger can evacuate exhaust gases more easily, which allows for more power
• better torque range, as the compressor can accelerate faster

Increased performance up to 10 kW (14 hp)

Euro 5 approval
