Arrow versus OEM muffler question

[Fatallybitten]

I have a full Arrow kit on my 2014 ES and have the ECU flashed for that set up. I also have a PCV and Autotune. What are the implications of switching back to the OEM muffler temporarily? You might ask why. The answer is to comply with a landowner's noise restriction ie: can't go on his property with an aftermarket muffler.

Even with the db-killer installed?

Bummer.

If I had to guess, it will probably run like crap (Too Rich)

Let us know how it goes!!

Engine will run cooler due to the rich mixture. You can adjust the CO settings to minus to make it leaner. Overly rich will foul the plugs but yours is short term, I would not worry too much.

Thanks. Anyone know if Autotune will make any fueling adjustments to lean it out?
