Exhaust Leak

[Brae]

I have an exhaust leak on my 01' SSEi and it sounds horrible, kind of like a moped going down the street or a really weak Harley, I believe it's from the front of the exhaust, probably the manifold but i'm unsure. If anyone has had a similar problem please let me know!

Best way to isolate it is to use a piece of vacuum hose as a stethoscope and find where it's leaking from, either under the hood or under the car.

Is there a video on this?

My guess would be the flex joint right behind the rear manifold.

That's my first guess. There's a donut gasket there that deteriorates.

I'm not aware of a video, it's pretty self-explanitory. Your dad probably has a mechanic's stethoscope in his shop too...

I think I have this problem as well. Does it sound similar to like a quiet chainsaw, or maybe like a buzzing whenever you accelerate? I've been wondering about that sound...

I ran a scanner on my car and it came up with an P0137 code. This is a Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2). I believe its being caused by an exhaust leak somewhere, mostly because of the buzzing sound I've been hearing when I accelerate. Anyone have this problem before? How do I test this?
