BMW G01 X3 M40i xDrive (B58 - 360 Hp - models avec OPF) 2017 -> (avec valve)

Supersprint is always a step ahead.

We already have developed a Turbo Downpipe kit for the 2019 BMW X3 M40i xDrive, with the OPF / particulate filter.

Our Downpipe kits are ready for sale, being available in multiple options.

We offer them with a HJS Motorsport 100 cpsi Kat, or with a HJS 200 cpsi high volume, 130mm Kat, and in a straight-thru, cat-deleting version.

Each one of the Supersprint downpipes is equipped with a plug-in port for the oem pressure sensor hose.

However, the low-resistence catalytics are not all there is to it; the perfectly shaped, smooth-radius merge cones (made out of strong, lightweight metal sheet, not cast) are equally instrumental to providing for a major reduction in exhaust gas backpressure over the stock catalytic; also, it is designed to bolt on and accept the dual barrel, M2 Competition-style std. OPF system.

Needless to say, the Turbo Downpipes are only the starting point for Supersprint.

In fact, our R&D crew is already working on a full exhaust system, including options which totally eliminate the OPF / particulate filter.
