I noticed my exhaust was blowing recently so decided to take it inot the garage to let the professionals have a look. Just got a call from them, and it appears both the Center and Rear sections have eroded and need replacing. What I heard afer that shocked me somewhat and all I can say is OUCH!!! Around £800 incl VAT and fitting to replace these parts. So have now decided to go aftermarket with a Milltek Cat-Back system, from AMD Tuning in Essex for £482 incl VAT and fitting. How can Renault charge such extortionate fees for a replacement exhaust is beyond me.
