Expect maybe a couple HP. It wont be a huge amount while maintaining the whole stock system. You should have a pretty small sound increase.

I have catless downpipes and will probably replace the secondary cats with resonators, but keeping the stock rear mufflers and stock mid muffler/resonator that comes with the E90.
