SUPERCIRCUIT has developed the catless downpipes kit and installed to the BMW F82 M4 twin turbo above. Here is the comparison of the factory stock downpipes and the catless ones.
The SUPERCIRCUIT catless downpipes are made with grade 304 mandrel bent stainless steel pipes and are fully TIG/Argon welded on CNC machined flanges which are also made from the same grade of stainless steel.
The below pictures show where the two turbo outlets are, on the BMW F82 M4 S55B30T0 3.0L mill, after the factory stock downpipes are removed from them.
Below are the closeup of the outlets. One of the turbo outlets are sitting high above the other.
The SUPERCIRCUIT downpipes are designed for direct bolt-on, no cut or weld is required for installation. At the top, it is clamped onto the BMW M4 turbo outlets by the original exhaust clamp (see below pictures).
At the other end of the SUPERCIRCUIT downpipes, they are bolted onto the rest of the BMW F82 M4 exhaust system as show in the pictures below.
