Exhaust Opel Astra

Exhaust parts for Vauxhall Astra cover various models including Astra H (2004-2015), Astra J (2009-2015), and Astra G Classic. Available parts include flexible exhaust pipes, stainless steel sport silencers, and complete catback exhaust lines suitable for petrol and diesel engines such as 1.3 CDTI, 1.4 16V, 1.6 Turbo, 1.7 CDTI, 1.8, 1.9 CDTI, and 2.0 16V engines.

Flexible exhaust pipes help absorb vibrations and thermal expansion between the engine, catalytic converter, and silencers. They come in various interior diameters (35mm, 45mm, 55mm, 60mm) and lengths from 100mm up to 300mm, designed as main exhaust system parts in Astra models like Astra J (2009-2013).

Performance exhaust silencers for Astra, such as stainless steel sport silencers, are made of high-quality INOX T304 stainless steel with TIG welding for durability and anti-corrosion. They offer improved power output and sporty or aggressive exhaust sound while reducing vibration and heat transfer. Common diameters for silencer outlets range from 73mm to 101mm, and exhaust lines carriers have diameters around 50-51mm.

• Fitment includes Astra H engines: 1.4 16V (90hp), 1.6 16V (105hp), 1.7 CDTI (80-100hp), 1.8 16V (125hp), 1.9 CDTI (120-150hp), and 2.0 16V (170hp).
• Plug & play installation without welding is typical.

The parts are engineered for direct replacement with no modifications required.

Catback exhaust lines include all components from the catalytic converter to the exhaust tailpipe and enhance performance and sound quality. For Astra J GTC 1.6L Turbo (2009-2015) and Astra H 1.9L CDTI (2004-2010), stainless steel (T304) lines are used, with 63.5mm (2.5") diameter piping and TIG welding for strength.

• Options include resonated silencers for moderate sporty sound or non-resonated for a more aggressive tone.
• Installation is plug & play with included fasteners and gaskets.
• Manufactured with quality standards in the UK (Sheffield) or equivalent European facilities.

These systems improve exhaust flow, may increase engine power, and provide a European-made product with durability advantages.

Yes, universal and OEM-style exhaust components exist for models like Astra G Classic and Astra H. For example, sport silencers and exhaust tailpipes around 850-860mm length are available with specific part references. They feature standard mounting collars and diameters fitting respective engine types, such as 52mm diameter for 1.3 CDTI Astra H engines.

• These parts match the original technical specifications ensuring proper fit and function.
• Suitable for repair or replacement in maintenance and exhaust system restoration.

Compatibility checks should be done using vehicle VIN and engine details.

The main material used is stainless steel grade T304 or SUS-304, known for high corrosion resistance and longevity. Precision TIG welding provides strong and clean joints. Mounting typically uses plug & play designs with included gaskets and fasteners, allowing installation without additional welding or modifications.

This approach reduces vibrations, thermal damage, and noise while ensuring performance enhancement.

• Diameter ranges from 35mm for flexible pipes up to 63.5mm or larger for performance catback lines
• Outlets vary between 73mm and 101mm depending on the model and engine configuration

These technical choices contribute to improved drivability and exhaust flow characteristics.

Exhaust parts are designed for multiple Astra generations, including:

• Astra H (2004-2015)
• Astra J (2009-2015)
• Astra G Classic

Engine compatibility ranges over petrol and diesel variants such as 1.3 CDTI, 1.4 16V, 1.6 Turbo, 1.7 CDTI, 1.8, 1.9 CDTI, and 2.0 16V producing between 80 and 170 horsepower. Models include options like VXR and various touring editions as well.

Always verify compatibility by VIN or detailed engine specs before installation.

Technical support, installation manuals, and compatibility confirmation by VIN are typically provided by the exhaust part supplier or manufacturer. It is recommended to have installation performed by qualified professionals to comply with technical and warranty conditions.

• Guides often include sensor positioning, mounting instructions, and torque specifications.
• Contact suppliers directly for tailored advice, especially concerning specific Astra models or engine variants.
• Ensure all replaced parts such as sensors and gaskets are compatible and installed correctly to avoid malfunctions.

Professional installation ensures best performance, sound quality, and compliance with European regulations.
