We offer wide range of exhaust system
products such as new developed products
with application of spinning and heat utilization,
catalytic converter, heat collector and muffler.
To obtain durability, black paint coating is applied to radiate heat from the exhaust manifold.
With ultra-small radius bending and spinning, this manifold is made to be compact.
This exhaust manifold is made suitable for integrated air injection system.
By designing the exhaust manifold with an inner pipe and an air gap between the two pipe layers for lower heat capacity, even better catalytic conversion is achieved. This is a design with the environment in mind.
We improve the durability of pipe for exhaust gas recirculation with the use of flexible pipes.
This is a system to trap exhaust particles from diesel engine. Sango's original PRS sizing technology allows it to keep high filtration rate.
It utilize ultra-small radius bending and spinning technologies.
By application of flexible tube and wire blade to absorb vibration, we improve its durability.
Using a spin-forming process, we are able to manufacture catalytic converter cases from a single piece of material.
This processing technique allows us to carry out highly accurate canning for diesel particulate filters (DPF), which require higher catalyst retention strength.
Two substrates of differing cross-sections (an oxidation catalyst and a filter) are canned in a single integrated case.
In response to stringent emissions regulations, this system contains elements with large diameter inlets/outlets, including an oxidation catalyst, DPF and SCR.
Within a limited space, it is designed to place exhaust manifold, oxidation catalyst, and DPF effectively. This clean diesel system meets strict emissions regulations.
By warming up the catalyst faster with the application of air gap pipes and exhaust manifolds with close-coupled converters, it contributes to filtrate emissions.
The entire muffler shell can be made from a single piece of material, without the use of welding and at lower cost. Besides straight spinning, muffler cones can be spun in eccentric or oblique designs.
By changing the exhaust gas flow within the muffler, we can achieve both the silencing of exhaust noise and lower back pressure, and with 20% less volume than a standard conventional muffler. It is operated solely by exhaust gas pressure.
With some expert tuning of the muffler and pipes, this aftermarket muffler provides consumers with the powerful, sensuous sound they desire, while also improving engine.
The muffler case is constructed with mechanical crimping (no welding).
Higher levels of productivity are achieved with the construction of muffler cases using laser welding.
By making muffler cases from stamped components, it allow us to reduce the number of components needed to build the muffler.
Muffler weight is significantly reduced with the use of titanium material.
Sango is a system integrator that supply products finding optimal combination of various parts to form a working system.
Dual mode mufflers, Spin-formed mufflers, Lock-seam mufflers, Spin-formed catalytic converters, Air Gap Pipe, Ball joints
Laser welded mufflers, Catalytic converters (made with spin forming), Ball joints, O2 sensor bosses

These devices reduce exhaust system vibration and help improve durability.
The air gap pipe bending products help with early light-off of the catalytic converter, as well as prevent heat damage to surrounding components.
We offer flat outlet and sharp angle designs. These products help cool the exhaust gas and some provide acoustic silencing functions.
With the use of hydroforming, it is possible to form exhaust gas paths with irregular cross-sections and complicated bends integrated into a single component made from one piece of material.
Sintering (powdered metal) allows a high degree of freedom in shape design.
