Lower Idle with new Axle Back Exhaust Install

[jimcalverley]

I installed an AFE Vulcan Axle-back exhaust for my 2023 2.7. It sounds positively EVIL (in a good way), without adding volume, which is what I wanted. However, I noticed that my warm idle is 500rpm, and with the stock exhaust it was 800rpm. Should I be concerned? While I was searching for precedent on this issue, I came a across an older post from a Toyota forum where several members told the OP that the truck's computer would adjust for it over a short period of time. Does that make sense? Will it go back up to 800 after a period? Should I even worry about it? If you've experienced this after installing a new aftermarket exhaust, thanks in advance for any wisdom you can pass on....

My idle is 500 rpm and my Bronco’s power train is 100% stock.

Sorry these V6's sound like ass, yours, mine, all of them.
I have yet to hear ANY aftermarket exhaust that changes my mind.

Anyway an exhaust, especially an axle back, is not going to effect your idle.

My 2.7 idles at 500 rpm when it's warmed up. It did that stock and the same with the FI axle back that's on it now.
