I think I have an exhaust leak but not sure exactly what it would sound like. It is mostly noticeable on deceleration and it sounds like someone is swirling a small metal ball inside a tin can. If I push the clutch in the sound stops when the RPM drops. It's only during deceleration where there is RPM above idle and it started immediately after my exhaust install. I also noticed two wet spots on the ground where the H-Pipe meets the aftercat. I also noticed if I put the exhaust in quiet mode the sound is virtually eliminated. I'm wondering if my midpipe is pushed in enough ( It is a Roush H-Pipe and sticks out about 1 & 1/8" from the header pipe clamp before it tapers up as shown ), if I should move my rear clamps slightly, rotate my rear clamps, apply more torque to all of the clamps, ( some kits say 22 foot pounds like mine and some say 80 foot pounds like flowmaster yet other people just use an impact) use a sealant of some kind, a combination of those things or something else. Just looking for general advice.
