Hi Guys- am new to your website & looking for advice on upgrading my Forrester 08/09 XT premium turbo's exhaust system. Am happy to part with a reasonable amount for the upgrade- but don't want to spend my next years wages on it either. Any advice on what l need to provide the 'Subi sound', approx.costings, who to talk to etc. would be greatly appreciated. Thanks in advance fellas.
