Where the middle bit of the exhaust meets the back box the exhaust pipe has split all the way round and come apart. i have it booked in to be fixed, but peugeot have told me it isn’t covered under warranty, is this right i have had it from new and its 30 months old? can i complain and kick up a fuss or are they within their right. it seams a bit unfair when all the rest of the underside of my car is in mint condition and the car has been treated well. surely this is poor workmanship?
