Nissan 370Z Forum - View Single Post - Fast Intentions exhaust is here! (continued)

After about a month, the exhaust has quieted down a lot (which is good IMO, exactly what I wanted). 18" res.

I find it interesting that some days it is quitter then others. I have not pinpointed a consistent reason for it.

I have also started to hear a pop pop sound when the revs are dropping. I know it is backfire, but not sure if anything can be done about it. Is it because the air/fuel ration has changed?
