Hi there!
I've been having a recurring and rather annoying issue with my Type-S for about a year now and am hoping to receive some input. Here is what I'm experiencing:
1. My car has been making a buzzing noise around 2-3k RPM when I accelerate. It's more noticeable when I step on the gas hard or am going up a hill, but is nonexistent if I'm just cruising on flat ground. The noise is intermittent and only happens sometimes. Once it starts, however, I can replicate it until I shut off the engine and stop driving. It seems like it's coming from the rear end of the car and goes away if I put a silencer in my muffler (I have a new GReddy Revolution RS muffler paired with a Magnaflow resonator and stainless steel pipe around six years old).
2. I've been noticing a whistling noise similar to that of a tea kettle. Similar to the buzzing sound, it disappears when I use a silencer and doesn't occur all the time. Unlike the buzz, however, the whistling is most noticeable when driving around 40-60 mph and is not affected by my RPM or how much throttle I'm applying. It appears to come from around the middle or even toward the front of the car and the noise goes away when I push in the clutch. It usually occurs for a few seconds, goes away, and comes back a little while later.
These are the two problems I've been having, and so far I've been unsuccessful in pinpointing why this is happening. The fact that both issues disappear once I install a silencer makes me believe that there's something going on with the exhaust system, but I could be wrong. I've already taken my car to a shop and looked at it myself; there doesn't seem to be any loose parts or areas where rattling can occur. As for the whistling, I'm at a complete loss. Any and all ideas or suggestions are greatly appreciated!
