BMW G30 530i Downpipe (B48 Engine)

When it comes to turbo downpipe collections, one has to pay us a visit to the SUPERCIRCUIT Exhaust Pro Shop for its large range of turbo downpipes on display, from the European marques to JDM models, from locally produced national cars to high performance imports.

Here is the latest BMW G30 530i with the B48 enigne that is installed with the SUPERCIRCUIT catless downpipe.

In the below picture, the 7th generation BMW G30 530i with the 2.0L turbo charged 4-cylinder mill code named B48B20.

The turbo outlet is located behind the engine and can be accessed via the undercarriage shown in the pictures below.

The factory stock downpipe is clamped onto the turbo outlet at the top and a slip-joint to connect it to the rest of the exhaust system at the bottom as shown in the picture below.

This is how the turbo outlet of the B48 engine on the BMW G30 530i looks like after the downpipe is removed (see below picture).

In the picture below, the factory stock downpipe of the BMW G30 530i vs. the SUPERCIRCUIT catless downpipe.

The SUPERCIRCUIT Downpipe is made of larger bore grade 304 stainless steel mandrel bent pipes and is fully TIG/Argon welded on CNC machined stainless steel flanges and it is designed for direct bolt-on application. No mod or weld is required during the installation, simply a direct swap.


The SUPERCIRCUIT Downpipe is clamped onto the BMW G30 530i turbo outlet at the front and connected to the rest of the exhaust system via a slip-joint at the rear as shown in the pictures below.

This catless downpipe is less restrictive compared to the factory stock one, it promotes better exhaust flow, faster turbo spooling and lesser turbo lag, hence a lot higher horsepower and torque can be achieved. It can also installed without having the ecu tuned, just add an 'O2 sensor' defouler to avoid the CEL will do the trick.
