BMW F30 320i (N20) Downpipe

Here is yet another BMW F30 320i at our installation bays for the SUPERCIRCUIT Catless Downpipe upgrades.

The factory stock original downpipe of the BMW F30 can be removed from the undercarriage fairly easily as indicated in the picture below.

This is how the turbo outlet of the N20B20 engine looks like after the factory stock downpipe is removed.

Moreover, 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.

The SUPERCIRCUIT Downpipe is designed for a direct swap with the original downpipe. The CNC machined stainless steel flange is clamped onto the turbo outlet of the N20B20 engine with the original exhaust clamp as shown in the picture below.

The bottom end of the SUPERCIRCUIT Downpipe is secured with a slip-joint clamp to the factory original cat-back exhaust system as shown in the pictures below. No further modification is required during the whole installation process.

The above SUPERCIRCUIT Catless Downpipes are designed for better exhaust flow efficiency, hence faster turbo spooling, lesser turbo lag, ideal for ecu remapping or tuning of the N20B20 engine!
