Hey guys im having this weird ticking sound from the exhaust when ever I start the car. Somtimes when I dont start the car for few hrs the ticking sound tends to get louder when ever I start the car. Also when I press the gas somtimes I hear like a whistling sound from the intake but it was never like that before. I can hear a sound differnce and a loss of power. What can I do to get this fixed? Should I just get a new exhaust?
