The Cobra Sport research and development team quickly made the decision to base the new performance exhaust systems on 2.5" (63.5mm) T304 stainless steel mandrel bent pipework. The system has been designed to run directly from the flange of the catalyst section running the full length of the vehicle finishing in a choice of tailpipe options.The new systems for the Corsa E 1.0 Turbo are based around a cat back configuration with the option for either a resonated cat back or louder Venom exhaust system. Sound testing revealed the two systems to have similar decibel reading for the external tests recording 96db and 97db on the static 4,000 rpm test. However, the resonated centre significantly reduced the interior cabin decibel reading recording 4.6db less at 79db than the Venom equivalent when cruising at motorway speeds. The outstanding improvements in sound quality are complemented by a significant weight advantage with the Cobra Sport system with increased bore size weighing only 11.86kg giving a 16% decrease from the OEM weight of 14.12kg.Cobra Sport Sales Manager Matt Thomas commented "We're very excited about the release of the system for the sporty 1 litre turbo edition of the Corsa E having had previously success with the Corsa E VXR and 1.4 Turbo edition. The pick of the systems for me is the resonated cat back exhaust which has been designed to improve the sound with an increase in volume whilst still having a perfectly balanced pitch and tone. The resonated section removes any drone from the vehicle interior at cruising speeds meaning you can have the best of both worlds with a dramatically improved exhaust sound whilst keeping this subtle enough for every day use of the vehicle."Cobra Sport have managed to improve the styling of the already sporty Corsa by finishing off the exhaust systems with a choice of bold highly polished stainless steel tailpipe options including 3.5" and 4" inward rolled baffled tips, a 3.5" outward rolled tip and a statement 4.5" x 3.5" oval slash cut tailpipe which we anticipate to be the most popular choice.
