Toyota Mark X 250G (X120) Exhaust Headers

We have developed a set of direct bolt-on sport exhaust headers for the 1st gen. Toyota Mark X (X120) with the 2.5L 4GR-FSE V6 engine here at SuperCircuit Exhaust Pro Shop, to remove the restriction and to improve the exhaust flow efficiecy for better engine output!

The factory stock original exhaust headers can be removed fairly easily from the undercarriage of the Toyota Mark X (X120) as shown in the picture below.

The below picture shows how the LH exhaust ports look like after the factory stock exhaust header is removed from the Toyota Mark X's 4GR-FSE V6 engine.

Shown in the picture below, the SUPERCIRCUIT Exhaust Headers vs. the Toyota Mark X (X120) factory stock original headers which come with two huge catalytic converters. These catless SUPERCIRCUIT headers are made with grade 304 mandrel bent stainless steel pipes and fully TIG/Argon welded on CNC machined stainless steel flanges for direct bolt-on application.

These are the flanges on the Toyota Mark X (X120) factory stock headers.

The SUPERCIRCUIT Exhaust Headers utilize stainless steel flanges and larger bore mandrel bent stainless steel pipes, then welded together with TIG/Argon welding for better exhaust flow efficiency and long lasting performance!

The SUPERCIRCUIT Exhaust Headers are designed for direct swap with the factory stock original Toyota Mark X (X120)'s exhaust headers as shown in the picture; they are also fully compatible with the factory stock original cat-back exhaust system, no further mod is required during the installation as shown in the pictures below.

The SUPERCIRCUIT Exhaust Headers are bolted onto the LH side (as shown in the below picture) and RH side (further down picture) of the Toyota Mark X (X120)'s 4GR-FSE V6 engine.
