Why is my 330 sounding like it's muffled ?

I have no res and no muffler. No cel nothing. It just the pops are so quiet now. Are there any reasons why? No power loss either just pops are super quiet.

Depends on the model year. The newer ones especially won't have pops/bangs so even with a straight pipe it won't really pop and bang like the 2020 models. If it does, it's gonna be pretty quiet.

Yes it’s 2020 it’s just been happening from time to time, sometimes it sounds super loud and other times it’s muffled.

For me depends on the temperature outside. Really cold days, I get the best pops.
