Stock exhaust 7th gear drone

Anyone else have this when the Jeep shifts into 7th gear around 2300 rpm I’m getting a drone from the exhaust.

I didn't hear any exhaust at all. I installed a Magnaflow dual cutback and sounds like it should have. The plus is it seems to breath better.

I have absolutely no drone from my stock exhaust. I tried 2 different exhaust systems with horrible drone results. the people that have removed the resonator and exhaust from ours add back in a resonator loop to remove drone.

Check for something touching your exhaust underneath. You could be hearing a vibration drone from something left loose by either the factory, or a repair shop.

If you don't find it, this is definitely not normal for stock exhaust.

I haven't noticed any drone. I'll pay attention today

I would agree with what others have said. If you have a drone with the stock exhaust, something is wrong. Stock exhaust has basically no sound at anytime.

No exhaust noise at all. Drives me nuts lol

Yep, could not replicate it in 7th anywhere from 2000-2500rpm.

Nope

Yeah it seems to happen in 7th when decelerating it’s like one spot so not that big of a deal, and I had my ears cleaned out recently so maybe just over sensitive

Could be a hole. Hate to say it but they are common in chrysler exhaust systems in my experience.

So I got under the Jeep and found a hole in the exhaust, is this covered under warranty or just get a shop to weld it

I would definitely look into it at a dealership but the other option would likely be quicker. Shouldn't hurt anything other than the sound.

Looks like they are just weep holes after doing some investigation, they are at the lowest point of each muffler

Neither. If you replace it your new one will have the same hole. If you weld it up the condensation will have no where to drain and the muffler will rust from the inside out. That hole is not the cause of the drone.

So I discovered that my tire size setting had changed back to stock after removing my tazer and was causing the transmission to hang in gears longer than supposed to and this was causing my drone
