Hey guys, I need some help for my accord. I heard some hissing noise while driving and sent the car to have it checked on.. the diagnosis is that the Muffler Gasket on the downpipe is destroyed, so I need to replace it. Unfortunately Honda parts is now closed fo the holy week, and I wanted to use the car during the holyweek. Does anyone know a quick fix for this? or is someone can direct me where I can get one or have one made.

Really appreciate all the help here.. the worst part is that I just had the sound system setup and wanted to enjoy a loong drive...

Car : Honda Accord 2.0L 2004 Model.
