Did a bit of sound deadening today using roof flashing tape. It's not perfect but it's helped a lot I plan on getting some more and giving the whole rear end a couple of layers to see if I get the noise down a little more
Before
After
The voids are also now packed with loft insulation as well
I also managed to stop an annoying rattle/vibration through the car that I've had since fitting my new down pipe by removing the heat sheild for the cat. Been a productive day by my standards
