SM Auto has Hi-tech manufacturing plants located in close proximity to manufacturing exhaust systems for scooters and motorcycles for Indian and overseas OEMs. The two-wheeler exhaust division has a full-fledged team of engineers who work in close collaboration with OEM R&D for the development of the exhaust system. The in-house engineering center has Catia, Finite Element Analysis (FEA), and Computational Fluid Dynamics (CFD) aided with an in-house tool room and the proto shop is used to support the development of these exhaust systems. SM Auto is now capable to manufacture BS6, Euro 6, and onwards compliant systems.

Robust manufacturing processes incorporating the latest manufacturing methods and equipment enable SM Auto to meet the stringent quality and emission requirements of OEMs.


SM Auto has an established design and development center fully equipped with advanced software for design, simulation, and analysis, and has successfully productized BS6 and Euro 6 exhaust systems. This engineering team collaborates with the R&D centers of our global partners to provide cutting-edge technology to our customers.

SM Auto has entered into multiple technical collaborations with Industry leaders in various vehicle segments to provide the most optimum solution to cater for the strict emission and acoustic norms.

A technical collaboration with Eberspaecher GmbH & Co.KG has been established to meet the latest Emission and Acoustic norms required for the passenger vehicles of Indian and Global OEMs operating in India. For the commercial vehicle segment, SM Auto has decades of experience manufacturing cold-end exhaust systems. A technical collaboration with Kavartherm, Germany has been also established to manufacture thermally insulated systems to meet the latest emission norms for commercial vehicles. SM Auto has also the necessary equipment to meet the customer’s demand. The facility houses multi-axis bending machines (also, 1D Bending), advanced canning cells, and forming machines.


SM Auto has entered a technical collaboration with Proventia Oy, Finland to design, validate and manufacture TREM IV & TREM V compliant exhaust after treatment (EAT) system for the Indian agriculture and construction vehicle segment. Proventia’s strong R&D department has allowed the company to gain exceptional expertise in SCR and Urea mixing technology. Its flexible urea mixing devices can be used with various urea dosing systems to solve any possible deposition issues and improve SCR performance in a variety of applications involving different engine sizes and operating environments. Proventia’s mixing technology enables the design of compact EAT systems for applications with constrained space requirements and can also be integrated with the DPF. These strengths of Proventia coupled with SM Auto’s extensive expertise in quality manufacturing will bring added value to customers.
