Audi S4 (B8) 3.0 V6 Catless Downpipes

We have installed a set of SUPERCIRCUIT catless downpipes to yet another Audi S4 (B8) supercharged 3.0L V6 here at the SuperCircuit Exhaust Pro Shop's installation bays.

The factory stock original downpipes can be found at both sides of the engine as indicated in the picture below.

In the picture below is how the LH exhaust outlet looks like after the downpipe is removed.

And the RH exhaust outlet after the downpipe is removed.

In the picture below, the SUPERCIRCUIT catless downpipes (left) vs. the factory stock original downpipes which come with huge catalytic converters.

The SUPERCIRCUIT catless downpipes are made of grade 304 mandrel bent stainless steel pipes with fully TIG/Argon welding on CNC machined flanges also made from the same grade of stainless steel materials.

Pictured below, the LH side installed. The SUPERCIRCUIT downpipes are designed to replace the original downpipes. Just straight bolt-on, no cut or weld is required.

The RH side installed.
