So I just got my 2014 R60 countryman a few months ago and I’ve realized that it’s too quiet for me! I'd like to remove the resonator and 2nd cat but don’t know the best place to buy pipes to put in place of the two. Any suggestions on where to buy and what pipe diameter to get?

I had swapped my downpipe in a stage 2 tune with the hi- flo catalytic converter from ministryauto https://ministryautostyle.com/new-pr...e86ayfh5qg5a8l
imo it's just loud enough before your neighbhors hate you
