My turbo blew up and i have had a refurbished one fitted to it.
Picked it up today after the garage phoned, but he did mention that the exhaust was blowing - more specifically from the mesh part of the cat.
Took it for a little drive and there is hardly any power, i put my foot flat and a little smoke came out back (oil got into exhaust, it did get cleaned out) there is the odd spike of boost, seems only higher in the rev range though.
He seems to think it is the cat blowing, he said that the mesh part was pissing out oil and water when he blasted it out with the pressure washer and cleaner. But i would have thought this would happen with it being mesh. Im not so sure its not a split pipe, although he said they all looked good.
Here's a video, what do you think?
