On my passenger side bank the injectors are making a lot of noise, some on the right but the left is making a lot of noise. Its enough to make me think it was an exhaust leak at first, is this normal or could it be a problem?

 

I trying to find help on the same problem

 

I mean I heard an impy that came into the shop the other day and it was silent, mine even with a stock exhaust would tick like crazy enough to make you think there was an exhaust leak... maybe its not a problem but Ide like to know, especially if it could be.
