Raw material selection: According to the design requirements of the exhaust pipe, high-quality stainless steel or aluminum alloy is selected to ensure the corrosion resistance and high temperature resistance of the product.
Material cutting: Use precision cutting equipment to cut metal materials into the required size and shape, ensuring smooth and burr free cutting edges.
Bending process: Using a CNC bending machine to bend the cut pipe into the shape required by the design drawings, ensuring the accuracy of the bending angle and radius.
Welding processing: Using advanced welding techniques (such as argon arc welding, resistance welding) to splice and weld pipes, ensuring the strength and sealing of the welded parts.
Rust removal and cleaning: Comprehensive rust removal treatment is carried out on welded exhaust pipes, usually using acid pickling or sandblasting processes to remove surface oxide layers and impurities.
Plating or coating: According to product requirements, the exhaust pipe is galvanized or sprayed with a high-temperature resistant coating to increase its corrosion resistance and aesthetics.
Component assembly: Assemble each exhaust pipe component (such as muffler, connecting pipe, tail pipe, etc.) according to the design requirements, ensuring that all parts are tightly matched without any looseness.
Air tightness test: Conduct an air tightness test on the assembled exhaust pipe to detect any leakage.
Performance testing: Conduct a series of performance tests, including exhaust flow rate, exhaust pressure, and noise testing, to ensure that the performance of the exhaust pipe meets the design standards.
Appearance inspection: Check the appearance quality of the exhaust pipe to ensure that the surface smoothness and welding quality meet the requirements and there are no obvious defects.
Dimensional inspection: Use precision measuring tools to conduct a comprehensive inspection of the dimensions of the exhaust pipe to ensure consistency with the design drawings.
Packaging: Professional packaging of qualified exhaust pipes, wrapped with protective materials to prevent damage during transportation.
Warehousing and shipping: Store the packaged exhaust pipes in the warehouse and ship them according to customer order requirements to ensure timely delivery.
We use the most advanced materials and technology to ensure that every customized exhaust pipe can provide excellent performance and durability. Whether it's the ultimate challenge on the track or the comfort experience in daily driving, our products can bring you significant improvements.
We focus on close cooperation with customers, from design to manufacturing and installation, ensuring excellence in every step. Our professional team will follow up throughout the process to ensure that your customized exhaust pipes perfectly meet your expectations and needs.
From the R&D department with sound engineering—and through the laboratories that manage and measure the materials and into the in-house titanium foundry and then to production, before evaluation and completion—the manufacture of an DemoSite exhaust is an internal journey with many facets that are all completed at the company’s state-of-the-art facilities.
Using only the highest standard of materials in the production of every Demo exhaust, our materials are thoroughly inspected upon arrival and assessed in the metallurgical laboratory. Though more than 30 years of experience working with titanium, stainless steel, carbon fibre, aluminium alloys, and more recently ceramics matrix composites, Demo sources only the best materials to produce its high-quality exhaust systems.
