Hello guys, new member here,
I have a 04 Track, with 170k miles on the dash.
Modifications: CAI, Borla Exhaust, Lightweight flywheel + stage 1 clutch, coilovers.

Recently I've been getting a knocking noise from under the car, while at idle.
the noise goes away when I hit about 1200rpm
I opened the hood and the noise doesn't seem to be coming from there, but when I put my head under the car the noise is apparent.
It doesn't matter if I'm in neutral or in gear, clutch in or out. the noise is there.

Also, I am getting a P1273, I don't know if it's related or not.
Please help me to diagnose this issue, I am worried

I'm not a master technician, but that sounds like a bad main bearing. Especially if it goes away as RPM's go up.
