You could buy downpipe with race or sport cats aswell.. With that there shouldnt be any inspection issues.. They are available for n54 so maybe for n20 aswell..

Why people go catless downpipes is because they are cheap.. and maybe you get a few extra hp compared to race/highflow cat downpipes...
But its mainly the cost. 200 for catless vs 500 or more for hiflow cats...
Also have read on forums that highflow cats dont last that long... not sure about that though.
