When I'm driving hard, and decelerating after pushing it, I get the customary pops and flashes in the exhaust. Now, one time when I was driving at night, I distinctly noticed a flash from under the car on the driver's side, right underneath me. I also think I hear exhaust escaping from the side of the car, but I'm not sure. I'm wondering what would cause this? Clogged cats? I have stock cats with a Bonez dp/mp and a Corksport cat-back. I haven't gotten a chance to look under the car because it's been raining in PA CONSTANTLY, but it's nice now, so I'm going to look today. I just want to know what to expect. ;P

 

One of your gaskets must have fallen apart. get under there and look around find the one joint(s) with no gasket and oder a new one.
