I installed a magnaflow exhaust on my 2016 LS 5.3 and loved it. Recently it started to rattle, traced the rattle to the butterfly valve. I called magnaflow and they sent me a new section of the exhaust with the butterfly valve on it, got it today and it seems the valve feels loose on this one too. Anybody have this problem with their magnaflow exhaust butterfly valve? Also, anybody figure out a way to jerry rig that valve permanently open?

I’ll try to take video of the rattle when I can.

Here’s the section they sent me with the butterfly valve 777ee561a2928f5cf9e1bdac442c58a3.jpg23fc799e462515b99607808ae071d6f6.jpg1b24a35f7beb74d7b72d73cc8d29bcfa.jpg


EDIT: Here’s the video of the new one.
