i got my isr y pipe with isr single exit on my 14’ coupe and it started making a weird vibration noise. ive checked like 10 times for leaks and im sure their isnt any, i took off the heat shields and it still does it between 2,500-2,000 rpm

 

ill put a video soon but if anyone can help me figure this out id appreciate it alot , ive only had the car for 2 months 50k miles and it bothers tf outta me lol

 

sorry the sound and quality is ***
