Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality. This Astra GTC 1.6 Turbo performance exhaust is made in 2.5"/63.5mm pipework and fit from the catalytic converter section backwards (cat-back) these exhausts replace the centre and rear sections. The resonated sports exhaust version includes the centre silencer and has a subtle but sporty tone. This exhaust however, is also available as a non-resonated version which is a louder option as it excludes the centre silencer and therefore, has a sportier exhaust note. All relevant fittings and gaskets are supplied. Please note: this product does not fit the 1.4 turbo model. Press Release The Astra GTC 1.6 Turbo is one which will always be on the list of cars regularly tuned and so Cobra Sport were eager to take advantage of the full tuning potential that this car offers. From the moment the car arrived, Cobra Sport wanted to add something a little bit special, with the de-cat and sports cat options and resonated and non-resonated options, a scintillating soundtrack can be created for those seeking a more powerful sound quality. The resonated cat-back upgrade provides a softer refinement that raises the game a little, without compromising on day-to-day usability. With the many fitment options available in this model it is certainly possible to tailor the exhaust upgrade to suit your own specific requirements. The Cobra Sport resonated cat back exhaust benefits from a very useful 29% weight saving when compared with the OE cat back system weighing in at only 12.94kg. The overall exhaust sound design certainly sets the car apart from the non-tuned versions, with the Cobra Sport resonated cat back system coming in at a sportier 4 dB sound increase and the non resonated variant at 6 dB increase, when compared to the standard cat back system. The full de-cat turbo back system increased the sound level at 4,000rpm to 85db, a 10db increase over the standard exhaust system.

Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality. This Astra VXR performance exhaust is made in 3"/76.2mm pipework and fit from the catalytic converter section backwards (cat-back) these exhausts replace the centre and rear sections. This sports exhaust is part of the Cobra Sport Venom range and is extremely loud. This part is sold for non road use only and will exceed all legal noise regulations. All relevant fittings and gaskets are supplied. Press Release Cobra Sport have expanded on their range of performance exhausts for the Vauxhall Astra J VXR by creating a Venom exhaust system which features simplified rear pipework for the ultimate improvements in both sound and performance. The OE system has been replaced with mandrel bent 3”/76.2mm bore T304 stainless steel pipework and is manufactured in Sheffield with beautifully bent pipework in place of the usual rear box to smooth gas flow and maximise possible performance gains. The simplified pipework of the Venom system has been designed to create an unrivalled deep sporty sound which will set the Astra J VXR ahead of the crowd. Sound testing of the finished Venom exhaust system when matched with additional first and second de-cat front pipes recorded an impressive 98db on the sound meter @ 4000rpm with a sound track which becomes highly aggressive under load. The Venom cat back system fitted with the O/E front pipes recorded a sound level of 89db on the same 4,000rpm static test. As with the other Astra J VXR exhaust system in the Cobra Sport range, the Venom system is finished with dual twin tailpipes which have been designed to subtly fit within the Astra's built in stainless steel exhaust outlets. The system is manufactured with 3"/76.2mm pipework which splits to two 2.25"/50.8mm arms to offer an outlet larger than 3" at the tailpipes. The intricate pipework bends and resonated centre section of the Venom exhaust system maintain the necessary back pressure within the system. Matt Thomas, Sales Manager at Cobra Sport offers his verdict on the Astra J VXR upgrade "Our new Venom exhaust is the ultimate upgrade for those looking for a quality of sound which beats any other system currently on the market. Following the success of our Venom exhausts for other vehicles in our range, we knew that the Venom system for the Astra J VXR would be a great match for the 2.0 turbocharged engine creating a sound which drew large crowds when demonstrated at the recent Performance Vauxhall Show." As always Cobra Sport are willing to back up their promises on quality, with a lifetime guarantee for customers who purchase the exhaust upgrade. Usual refinements include, hand finishing using advanced TIG welding techniques and all Grade 304 stainless pipework being formed expertly on CNC Mandrel bending machines, which ensures the smoothest of gas flow, with precision jig manufacturing to ensure a perfect fit.
