Magnaflow exhaust questions

So I'm thinking of purchasing a magnaflow exhaust system for my 2001 bmw 325ci. As of now, they only mods I have to the car are: tinted windows, a coilover kit, carbon black grill inserts, xenon sidelights, and angel eyes. I'm not as experienced with engine mods, etc.. So I was just wondering how many extra horses I would get out of the magnaflow kit compared to the stock exhaust system, if Ill even get any extra horses at all.

you won't get anything out of it really. but the entire exhaust will be a heck of a lot lighter than the stock one. and it'll sound good.

HP comes from replacing the main choke point - the header/cat with Magnaflow's improved replacement. Look at an OEM version and you will quickly see why. This assumes that the cats are required.

Cat back exhaust benefit:
NA cars = lighter weight and sound only as OEM flows okay
FI cars = more HP when ideal back pressure is found.

Search and learn before you spend your money.

Kind of late but I currently have the catback magnaflow exhaust which cost me like $750. Did not notice anything performance-wise but I definitely enjoy the sound of my car despite having an leak cause i somehow broke one of the studs off... Everything is bolt on too so you can just do everything in your garage yourself also.
