I checked all the pipes and tightened all the clamps. My engine also has a fast ticking sound coming from the engine. I don't remember it sounding like that when I first bought it last month. It is still under warranty and I highly doubt within a few weeks that it would be spark plugs. It definitely seems like the Stillen is at fault. I'm debating taking it off bc my car is definitely slower >3K RPMs.
