I can do a video of my new truck. 5.4 4v with no cats and a single in single out 22" magnaflow. I'll try to get it this week sometime.
I'll do a video of mine when it stops raining. I'm running 2.5" pipe with a cheap amazon cat and a thrush glasspack. Used to have a down pipe but it fell off Insert tab A into slot B and........pound it with a hammer!
