Tomei Expreme Big Mouth Turbo Outlet/Front Pipe

After testing a variety of shapes and pipe diameters at the Tomei R&D Lab, they found the optimum tuning point for the best performance balance. This design will extract the full capabilities from the EVO X 4B11 engine. The design also retains the original layout to help with the ease of installation and compatibility with other exhaust parts.

WIDE MOUTH

The smooth flowing design, without steps from the turbocharger. Manufactured with the lost wax process, combines both strength and beauty.

3 INCH PIPE

After numerous tests, the 3 inches (76.3mm) greatly increases both power and torque.

GOOD DESIGN FOR TOOLS

The wide mouth was designed to be easy to install with the general common work tools.

O2 SENSOR BOSS FOR AFR GAUGES

The mouting boss is an M18, which makes it easy to fit the AFR sensor. Comes with a blind plug to seal the hole when not in use.

FLEXIBLE PIPE DESIGN

Easy to install with minimal risks to cracking the stainless steel exhaust manifolds from vibrations.
