Performance: R53 Mini Cooper S Stainless Steel Back Box

[JonnyM]

I have this of my own R53 Mini, I am only changing it as I will be running an R56 exhaust now. It’s loud but probably only because I have no other boxes in my exhaust! I don’t know what make it is as there are no markings on the box or tailpipe but someone said due to the style etc it could be an Alta Performance exhaust.

Not in my car as I have the battery box cut out and made a flat floor.

That should sound really well as with the bigger bore you should get a nice deep note.
