I don't believe there's many members running this setup or other aftermarket downpipes with stock exhaust. Long story short...I finally got around to installing my downpipes and now think there's a potential exhaust leak. HOWEVER it only happens when it's reaching normal operating temperature. I will be going back to clean the slip on exhaust piece that connects the downpipe and stock exhaust. I was too hyped when installing and should have sanded down the rear exhaust pipe to ensure a clean fit.

Is there any feedback from others that have experienced similar issues?

Thanks
