SUPERCIRCUIT Exhaust Pro Shop has probably the largest collection of turbo downpipes for the BMW marques from the high performance M to the diesel engines. Here is one installed to the BMW F30 320i with the B48 engine.
This is the BMW B48B20A turbocharged straight-4 petrol engine (Picture below) which replaces the earlier version of the BMW F30 N20 engine.
This is how the turbo outlet of the BMW B48 engine looks like after the factory stock turbo is removed.
The SUPERCIRCUIT catless downpipe vs. the BMW F30 320i (B48) factory stock downpipe (Below Pictures). The factory stock downpipe comes with a huge catalytic converter chamber which is very restrictive to the exhaust flow.
The SUPERCIRCUIT Downpipe is designed for direct fit-on to the BMW F30 320i B48 turbo oulet via the original exhaust clamp as shown in the pictures below.
At the other end of the SUPERCIRCUIT downpipe, it is a slip-on joint which is also compatible with the factory stock BMW F30 320i (B48) catback exhaust system. No cut or weld is required during the installation process.
The SUPERCIRCUIT catless downpipe is made with grade 304 mandrel bent stainless steel pipes and is fully TIG/Argon welded on CNC machined flange which is also made with the same grade of material.
The catless downpipe is a lot less restrictive, promotes better exhaust flow hence better torque and horsepower can be achieved. It is also ideal for ecu tuning or remapping needs.
