Default Are You Getting a Grinding Noise @ 2-3k RPMS??

So my car started making this screeching/grinding noise at exactly 2250 RPM and if i hold the pedal at that rpm.. it will continue to grind.

Turns out that two brackets that are above the y pipe were broken and they were causing the grinding noise. The shop that I went to was the same that did my entire exhaust so they know me pretty good -- they didnt charge me anything for this. Apparently, many 6th gens experience this issue sometime or the other.

So if you ever get this prob, just get the bracket re-welded back or jst remove it.

i noticed a tinny rattling noise at low rpms on my car recently with the windows down. it's not very loud, but i can hear it when driving by walls and curbs. i checked my exhaust gussets and they look fine. i did notice that the flex tubes on my cattman y-pipe are pretty close to each other. i'm wondering if those are somehow vibrating against each other under low load.

I also had this problem. i had grinding/rattling noise at low rpm and at high rpm as well. This noise was annoying and it's common on maximas. Took my car several to the dealership and never told me it was normal. Basically, to deal with it. They told me to use a thicker oil and better gas. I'm already using synthetic and 93. They finally found where the noise was coming from. They replace the rack and pinion. And fellas, the noise is gone!!!!

The labor cost was 671.30.
The parts amount was 1408.07

I didn't paid a cent because i have the extended warranty. If you have extended warranty and have the same problem, take advance of it.

Is this something on the Y-Pipe itself or something on the car above it? I have this exact noise and was afraid it was something in the engine. Anyone have pics of this piece? Thanks.

This problem drove me nuts when I had it, broken gusset. Shop welded back in place when I had my Y-Pipe installed. Good info.

I dont have a pic on the car but I have these.

I cheaped out and had it welded, it broke again, just bought a new one, been fine ever since. I think they made the new brackets stronger.
