Fitted a new can to my K5.
Came from SP Engineering.
I'm running it with the baffle in as without, it's extremely loud !!
I also took the OE can apart, retrieved the catalytic convertor, removed it from it's housing, then inserted it into the link pipe just before the new can, so I can at least pretend I'm trying to save trees or people or something.
Quick video of the sound, revved up to around 5k....sorry about angles, I was just walking about with my phone camera.
