If you are looking for a performance back box for your Vauxhall Astra, Calibra, Cavalier, Corsa, Nova, Tigra, Vectra or Zafira then we have you covered.  Our range includes products made by Sportex, Scorpion, Piper, Supersprint and Ulter Sport.  While our exhaust back boxes will give small power gains they are usually bought for their good looks with a choice of tail pipe design and their sports sound exhaust note.  Most are an easy DIY fit simply replacing the original back box. The material used to build these exhausts is usually high quality stainless steel and or aluminised steel.  Most are guaranteed for as long as you own the exhaust.  Full exhaust systems and exhaust manifolds are available for some models.  Our performance exhaust guide gives further information on our Vauxhall rear silencers
