Exhaust leak at the flex pipe - bad?

[Deadly BlaZe]

I have an exhaust leak at the flex pipe, besides the car being noisy, does it hurt anything at all?

Nope, past the turbo and O2 sensor so theres no problem. The only thing I could think of is that it may melt something if it's big enough without a heat shield.

As long as you don't have a wideband o2 installed past the leak you are OK. A leak before the W/B will read lean.

ok thanks guys.

Might cause some unnecessary back pressure oh no....

Itll be just fine.

it still throws off your o2's and logs lean. I too have a fucced flex pipe and im going to weld in a longer one to hopfully fix my wacky readings. i was loging through dsmlink by the way so its an acurate senerio.
