Yes. Hissing from the midpipe to dp. Was a bad new gasket when i replaced it. I used a regular donut with a 3" two bolt graphite gasket around it to seal the extra bits from the 3 " to 2.5" connection. The 2 bolt fit perfectly around the donut gasket.
The gasket it came with was still leaking even torqued past max specs.
Retorque your midpipe and axelback connections and put the top of your hand all around the flanges to check for a slight feeling of escaping gasses thru the gasket. (Right after cold starting) dont burn yourself!
