Behind the insane annoying rasp and loudness, I can hear that high pitch ever so slightly. I will try to wield on some 300 CPSI cats to see if it will help.

The rasp is so bad that I assumed there were massive exhaust leaks or something. But a separate exhaust shop verified no exhaust leaks or the exhaust touching anything it shouldn't on the frame/heat shields. Super disappointed ngl.

If anyone has any advice feel free to share lol.
Can you send me exhaust clips of current setup? I was thinking of going 200 cell cats that CEES sells them with. Basically mimicking another YouTubers setup from a different (Chinese) brand. I hope the rasp isn’t a problem with this setup.
