Mitsubishi Lancer 2.0 (4B11) Exhaust Header

We have produced hundreds if not thousand of the exhaust headers for the Mitsubishi Lancer 2.0/ Proton Inspira 2.0 (4B11 engine) locally and internationally todate. Here is one we have just installed at our installation bays.

The original exhaust header can be found behind the Mitsubishi Lancer 2.0 (4B11) engine, just in front of the firewall, as indicated in the picture below.

This is how the exhaust ports look like on the outgoing Mitsubishi's 2.0L engine (codename 4B11), after the original exhaust header is removed.

Pictured below, the factory stock header of the Mitsubishi Lancer 2.0 (4B11) vs. the high performance SUPERCIRCUIT 4-2-1 header in full stainless steel! The SUPERCIRCUIT header is fabricated with tuned-length primary pipes and long secondary pipes for both improved low-end torque and high-end horsepower.

The extra bonus feature of the SUPERCIRCUIT Exhaust Header made for the 4B11 engine is that it is also compatible with the original heat shield. The original heat shield can transferred to the SUPERCIRCUIT header during the installation, for both aesthetic and head managment at the engine bay!

In the below picture, under the heat shield (which is transferred from the original header), is the tuned-length high performance SUPERCIRCUIT 4-2-1 header!!

The SUPERCIRCUIT 4-2-1 high performance exhaust header made for the Mit. Lancer 2.0 (4B11) is fabricated in full 304 mandrel bent pipes & hand TIG/ARgon welded by the master craftsmen here at the SUPERCIRCUIT Exhaust Pro Shop.

There are five bolts that secure the header back in place onto the Mit. Lancer 4B11 engine block. Don't forget to reuse the original metal gasket too!
