anyone know where i can get a mesh grill with the logo like this? cant find anywhere 😢

hello again reddit. For context i have a 2010 g37x sedan, 210k miles. since i bought the car in august ive had a problem where after decel and trying to tip back into throttle, my exhaust makes a very deep noise and the rpms seem as if it doesnt want to raise (as you'll see in the video.) i have a isr catback so theres no reason for a deep tone. the issue goes away as soon as i go into full throttle. any idea what the issue can be ? i've been trying to fix this problem so i can get tuned, i already replaced OEM spark plugs and coils, Bank 1 vvt solenoid (prior p0011 and p0300 codes that never came back, but replaced the solenoid anyway with oem), cleaned throttle bodies, maf sensors, and done all the necessary relearns. PLEASE guys i need to fix this issue and the g is perfect 🙏🏽 (no codes other than p0456 for gas cap i think).
