Rattling Noise Help

[Tat2bass]

So, a couple days ago I noticed a rattling noise. Sounds like metal on metal and is vibration based. It only happens at exactly 2500rpm. I had noticed when I first got the car there was a resonant frequency vibration at that point, and it got more pronounced when I put in the Lethal Catless mid pipes. I've had the pipes on for about 2-3 weeks with no issue. Then the other night I was stuck in traffic and started noticing the noise. It doesn't happen every time, maybe about 50% of the time. I tried seeing if it was based on how hard I would take off but it seems to be random, but again, it only happens at exactly 2500rpm. Has anyone else had this issue, and if so, what was it? I lifted the car last night and retightened all the bolts on the exhaust and it was still there after. Sounds like it is coming from the engine or under the car towards the front area. Ran a diagnostic check as well and nothing popped up. Car doesn't feel or drive any different either

I've had my car though for two months now and it's never made this noise. Don't get why if that is it, it wouldn't show up until nearly two months in and 5600 miles later. I know that this motor design inherently sounds different and I could tell the different sound, but this doesn't sound like piston Rattling to me. It also doesn't get any louder when the exhaust valves are open. And being I'm catless, I would assume the noise would be louder when in sport mode.

I'll take a video in the morning to try and catch the noise.

just because they all do it, doesn't mean that something isn't wrong.

Here is a sound clip of it.

Got it up on a lift. I was in the car revving it while my friend was underneath. He said it was coming from inside the transmission housing. So took it to Galpin and we will see what they say. I'll keep this updated so others can search if anyone else runs into the same issue
