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, the power is higher than the stock muffler from the low rotation range to the high rotation range, and the torque is also higher in almost all areas, so it is comfortable even in towns where there are many stop-and-go.
In comparison to the power peak value, the genuine 85PS, Shizuka Gozen muffler is 87.32PS. The difference is 2.32PS, which is a big improvement!

Features of Shizuka Gozen muffler for Jimny Sierra JB74

[Compatible with genuine bumpers and Apio bumpers]
Can be installed on Jimny Sierra JB74 genuine rear bumper without processing!
With exquisite thickness and handling, it matches not only the genuine bumper but also the combination with the Apio tactical rear bumper without any discomfort.
Although it is a simple exit that suppresses claims, the muffler sound that can be heard from there is not the genuine ratio.

[3-piece structure]

Unlike JB64, Jimny Sierra JB74 has a silencer on the genuine front pipe. Our company’s muffler “Shizuka Gozen” for JB74 has replaced the front muffler, and has a three-part structure of “front muffler”, “center pipe” and “rear muffler”. Exhaust efficiency has been greatly improved, and a 1.5L naturally aspirated vehicle has achieved an increase of more than 2 horsepower.

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

Both Jimny JB74-MT and AT vehicles have passed the pre-test and are compatible with the pre-certification system of the new muffler standard. A certification plate is welded to the product.

[ 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.
