Dynapack power tester results

Dynapack power test graph
Measured with a Dynapack power tester on the same vehicle with the genuine muffler and with the Shizuka Gozen muffler installed. When the Shizuka Gozen muffler is installed, both torque and power surpass the genuine muffler from the low rotation range to the high rotation range. In a comparison of the power peak value, compared to the genuine 52.938PS, the Shizuka Gozen muffler is 54.014PS, which is an increase of 1.076PS.

Features of Shizuka Gozen muffler for Jimny Sierra JB74
The Shizuka Gozen muffler matches the genuine rear bumper of the Jimny JB64. Although the product configuration is only a rear piece, it achieves the high performance of quiet performance and power up.

[Proof of compliance with the new standard “certification plate”]

A certification plate is welded under the drum. Both Jimny JB64-MT and AT vehicles have passed the pre-test and are compatible with the pre-certification system of the new muffler standard.

[ Curl end and tone hole ]

The outlet has a double pipe structure that is also a feature of the Apio muffler. It is safe because the outer cylinder does not become hot. In addition, the curled end method with the outlet part rolled inward will not hurt your clothes or skin even if it comes in contact with it.
A tone hole is installed at the bottom of the outer cylinder to eliminate the muffled exhaust sound.

[Built-in “jet stream fin”]

The jet stream fin, which is the biggest feature of the series, is installed inside the Apio Shizuka Gozen muffler series.
In the low rpm range, it prevents over-disengagement and increases torque, and in the middle and high rpm range, it creates a vortex effect on the exhaust, greatly increasing the exhaust flow velocity. This effect achieves a wonderful blow-up and response.

In addition, the inner part of the muffler is made of stainless steel mesh, which has excellent corrosion resistance and is wrapped in super glass wool to achieve both excellent exhaust efficiency and noise reduction effect.
