This well engineered performance exhaust fits as a direct replacement for the original part on all Astra MK5 (180bhp) 1.6 Turbo (3 & 5 door) Hatch models built in the date range 2005 - 2010. The Sportex systems and tailboxes are manufactured from aluminised mild steel with polished T304 stainless steel tailpipes. The silencers are of the straight through absorption design giving a subtle deeper more hollow exhaust note without intruding on in-car noise levels! All Sportex tailboxes and systems are now made on state on the art CNC bending machines so you can be sure of a perfect fit every time.
