(i'm french) english not perfect.

Hi,

The 29 July 2017, i start the car in the morning and i noticed exhaust leak in front never noticed this before.

Is frequent problem on echo HB 2005 and yaris, platz ... exhaust leak in front ? 123 000km on it clean echo but sound crap since 29 july 2017 i don't know what is the cause, the car drive in quebec, rust problem? A little bit hit pedal gas and sound increase. A few shots of gas in neutral, and problem begins, small leak begin loud. The sound of the leak is more loud, after HWY ride Montreal-Quebec. 120-125 km h

i put brandnew back exhaust in 2016 for 500$, now the problem repeat in front.
gasket problem? headers ? exhaust under is not disconnected.

I can leave it like that?
Police ticket? Carbon monoxide? this leak disturbs the 1nz-fe?
