Car suddenly sounds quieter??....
Hello, I have a G35 sedan and i have been running it with a resonator and muffler delete for the past year and about two days ago i noticed that car sounded a lot quieter than it normally is. I have had no recent maintenance done to the car whatsoever. The only thing to note is that i noticed my car was quieter after getting some gas. Could bad gas somehow cause the car to sound quieter? Friend suggested it could be my catalytic converters. Anyone else ever had this issue?

Not necessarily, the downstream sensors won't throw a code until the data they're sending is out of spec. You can have melted spots in the cats and still have a running engine, Is there any chance that you got a bunch of water up into the muffler or something? I've seen wierd things happen like people parking right next to a high pressure sprinkler in a park that actually worked water back up into a muffler although it wasn't really a "muffled" sound it just sounded like complete **** and was belching water out when he was on the throttle. Took a week to finally get it all evaporated though.
