APPLICATION

EVO 10

After testing a variety of shapes and pipe diameters here at Tomei R&D Lab, we found the optimum tuning point for the best performance balance. This design will extract the full capabilities from the EVO 10 4B11 engine. The design also retains the original layout to help with the ease of installation and compatibility for 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.

Wide mouth & 3 inch piping. Achieve large power & torque gains over stock.

Direct bolt on that retains the original stock layout.

Lost Wax casting process for maximum durability,

precision without welds.

Larger in size and diameter, smooth

without any steps.

The larger curve design makes it possible

for a much larger capacity.

Improved efficiency through with

a more linear layout.

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.

MIKALOR HIGH GRADE BANDS

The Supra Bands made by MIKALOR is what we have chosen to use, since they maintain the strongest torque to secure a proper strong connection. We also used Nejiname bolts.
