problem... is it serious?
Leaving out of pizza hut my exhaust noise changed big time, it got deeper and started to back fire. I can hear this vaccume noise almost like a supercharger whistle its coming from the timming chain cover and its annoying and I dont know the cause of it. Is this Serious?
p.s by the time I got home my exhaust went back to normal and the temp outside is like 5 deg.

It sounded like I had a Civic exhaust on, I felt so embarsed to be driving in traffic sounding like ****. It could be it, and I already changed my rear engine mount yet when I put my car into rev or 1st gear and get it moving I hear a clank noise as if an engine mount was loose.

I went to my mechanic shop today and Well I also told them I heard this supercharger/turbo sound and that my exhaust sound changed, they lifted up the car and noticed a gasket between the cat. and catback was broken. They changed it and noticed i was missing a bolt on the Y-pipe, they put a bolt in there and now my car is very quite and smooth. But I still get this noise when I rev from 1-2K Its a very load turbo like noise. It dies out when the car hits 3k+. Anyone else have an idea?

Full exhaust was checked from headers down to the end. 2 gaskets were changed on the cat, and a bolt that connects the front header to the y-pipe was missing, once he put that bolt on the front end got very nice and quiet. No leaks because they double checked. This turbo/Vaccume sound noise comes from the timing chain cover/belts/pullies around that area. The engine can be cold or fully warmed up and It will make this sound. Its very annoying, I got stopped twice because other maximas thought I had a turbo. Last time I checked there wasnt one install in my car lol. anyway Its hard to discribe it, Its more or less a hissing, turbo sound or a vac sound as in air is being sucked in or leaking.

then the problem must be in that area, I guess check all vacuum lines make sure everything is tightened, nothing loose, or have a crack/hole in it. it should be too hard to find if other cars driving by can hear it, start the car and look around, should find it in no time.
