I have a stock 09 135i vert...its gonna be the first upgrade just havent decided which one to go with...any suggestions?

Why start with the midpipe? If its sound youre looking for an axleback will do you much better.

Do you have a auto or manual?

BERK. If you go N55 and later add kittyless downpipes you will have a ton of rasp. The Berk ones have a resonator in them that really cuts down on rasp

N55 mids have a single large resonator but I think Berk has two, right?

I think the berk street axle back isnt much louder than stock and the muffler delete ine is too loud. Midpipes change sound a bit and somewhat "increase" power cus of the cats being gone from what i understand.
