HJS downpipe EURO 6 ECE approval suitable for F2x F3x F87 M2 BMW

This HJS tuning “downpipe” is designed for BMW 1-4 series with the new Euro 6 N55B30A engines. No reprogramming of the engine control is necessary .

The significantly reduced exhaust back pressure of the HJS tuning catalyst not only reduces temperatures in the turbocharger, but also significantly improves the engine's response . Of course, the improvement in power and torque is clearly noticeable. And last but not least, the metal carrier used also ensures a more sonorous sound.

Expected performance increase of approx. 10 hp for standard vehicle (see diagram)

With the ECE approval, an entry in the vehicle documents is not necessary.

We recommend replacing the V-band clamp with metal seal. You can find this here .
