Peugeot 307 engine is giving weird, heavy noise when i step on the gas peddle

Car: Peugeot 307
Variant: 1.6 petrol
Model Year: 2003
Categories: Running Rough, Starting & Power Loss
Car engine started to give heavy, hoarse noise when accelerating. When car is going and I'm not pressing the gas - it's fine. ALso it started to smell when I increases accelerationa and was back fine when I stopped. What can that be?

Clutch slipping ?

No, just engine is working differently, much noisier than before while pressing on gas peddle. I'm no speeding or driving quickly, it just the more rpm the heavier engine works. It started yesterday. Timing Belt was changed last year so it shouldn't be it. Any ideas?

Exhaust blowing or air filter housing come loose?
