Riss racing is a 3" single pipe, easy to adapt to 128i. for 130i maybe you need a custom approach or use a e82 mid pipe from any source( n55, riss racing) and 130i muffler
For more details of the set up that i got, please look up user Pushkin and his My 128i thread. He has the details there.

Fyi 130i exhaust pipe and routing is identical to 128/330 etc - not even a little drone for me, but i have a fully open hatch layout, different resonance lol , is audible but not LOUD inside
