Recently my prelude 92 engine sounds noisier than usual. It never happen before. The car is still running. Please help.

 

More info on noise? Type of noise? When does it do it? During a certain rpm range.

More info and we can probably help ya out.

 

The car was running good (not loud). Until 2 days ago, I have tried to go to 100 miles/hr. Then I heard the engine running noisier than usual. Rightnow, it is very noise at every running mode including when the car is at iddle. I still can go up to 100 miles/hr at 4500 rpm. But it is very noisy. I wonder there is any broken component in the engine. Please help

 

Is it a metallic noise? Is it coming from the head or block that you can tell? It could possibly be the valves and they may just need an adjustment.

 

I found out the exhaust pipe between exhaust manifold and the Cat. broken. Do you know where can I get it? What is it call? Thanks

 

Think it's known as the "downpipe" if your after the stock one you will probably need to visit the Honda dealers.
