I didn’t notice much with the dynomax, honestly. I had to get rid of xx-pipe and go back to a mid muffler (solo cyclone) to get the sound reduction I was looking for.
My axle back is 2 helmholtz resonators only so it got pretty loud.
This is what's recommended on a throttle body install, assume it's the same:
Idle for 5 minutes in Neutral
Idle for 1 minute with A/C on
As for a full PCM relearn, you can look up "KAM reset" and find the procedures. This includes fuel trims and distance to empty on your dashboard
Any good options for a center muffler that can be welded in? I have a super aggressive axle back currently uninstalled since I added an X pipe.
Looked at vibrant 1794 or two magnaflow bullets. Not sure if that provides any meaningful volume reduction.
Any opinion on something like this?
Full catback system for sale, whole or by piece.
