Just curious to see if maybe anyone else has this problem on their older gsr, or if its a problem specific to my car (which is probably the case). I know that things like this are impossible to diagnose, especially given my mods, the noise could be coming from anywhere from the headers or the exhaust...however, its always sort of been there, even before the mods. around 4300/4400 is the "annoying" spot in the gsr rev band in that it hasn't changed to vtec yet, and if you are light on the gas, the car gets sooooo buzzy in this range. Has anyone else experienced this? Could it be the cat?

Let me know,

Thanks

 

most likely the notorious heat shield...

 

how notorious? heat shield on the cat? should i just rip them off?

 

yes, its the shields.
do a search..
