BMW F25 X3 (N20) Downpipe

The SUPERCIRCUIT catless downpipe supplied and installed to the 2nd generation BMW X3 (2010-2017; F25) featured below is designed for an unrestrictive exhaust flow. The improved exhaust flow efficiency of the catless downpipe is ideal for ecu remapping or tuning purposes!

In the picture below, the stainless steel SUPERCIRCUIT Catless Downpipe VS. the BMW F25 X3 factory stock original downpipe which has a huge catalytic converter.

The SUPERCIRCUIT Downpipe is made of grade 304 mandrel bent stainless steel pipes and fully TIG/Argon welded on CNC machined flange for long lasting performance and durability.

Pictured below, the turbo outlet on the BMW F25 X3 after the factory stock downpipe is removed from the N20B20 engine.

The SUPERCIRCUIT Downpipe is designed for direct bolt-on application. It is installed to the F25 BMW X3's turbo outlet via the original exhaust clamp as shown in the picture below.

At the other end of the SUPERCIRCUIT Downpipe, it is secured with a slip-joint clamp to the factory stock original F25 BMW X3's cat-back exhaust system as shown below.

The above SUPERCIRCUIT Catless Downpipes are designed for better exhaust flow efficiency, hence faster turbo spooling, lesser turbo lag for the F25 BMW X3's N20B20 engine.
