The bloke whos repaired the car has mentioned that the back box is likely to need replacing in the not too distant future (recons 12 months max). Should I just replace with standard SRI back box from vauxhall or is there something more interesting out there? Being a diesel there's no grunt from the exhaust so its all about looks.... perhaps a second hand GSI twin?..

Im only asking now as we've been dealt a fairly heavy blow by Mr Cameron's 'in this to together' crap and it's likely to take 12 months to save up to replace the exhaust!
