Hi I have a slight blow from the rear silencer on start up of the car and when revving, can anyone point me in the right direction of where to find the right part. Eurocar parts and similar are showing nothing.. it's a 1.8 petrol 2012 plate, cheers

 

Are you saying you have an exhaust leak near the rear muffler?

If so then exhaust parts should be easy to come by for your car from pretty much any local parts store, an exhaust specialty shop, or of course, your local Mazda dealership.
