Hi everyone. My car is making a loud blowy noise, coming from the front. Just had my car looked at by a local garage and they have said that there is a hole/crack in the pipe that leads from the manifold to the Catalytic Coverter. They're saying that I need a new manifold and that it's a massive job. Been quoted roughly £950, inc parts and labour. Getting it looked at by another local garage for a second opinion on Monday. Does this sound about right? Just need some general advice please on what to do and what the caused this (probably my heavy right foot). Apologies for my lack of mechanical knowledge and thank you in advance.
