Hi all. So I just had my muffler replaced and while I was there they told me my exhaust manifold was cracked. I can't afford to replace that at the moment so I just had the muffler replaced for now. I am getting this awful ricey honda noise now when I excellerate from my new muffler that wasn't like that before. Is it from the manifold being cracked or is it something else. In addition I have this clicking noise coming from the front of my car that sounds a bit like a jetsons flyer. It isn't a low oil thing cause I have been very good at changing the oil. Would replacing the manifold fix this noise as well?
