Need help Lancer 2010
 

Hi i recently bought myself a Mitsubishi lancer 2010 model, 1.5L sportback.
In all my years i never had a mitsubishi. So i got a question about exhaust.
Becouse i spent alot of money on the car and im afraid something is wrong.

Is it normal that the exhaust makes farting noise in the front when accelerating between 2500 rpm and 3000 rpm.
The sound sounds like a mildly sport sound, like an leakage, but i only hear it in the front.
The wierd thing is that when i park the car put in neutral and accelerate, i cant hear any noise.
IS this normal ?
Does the exhaust make this kind of noise ?
