Horse power gain from mods?

Hi there!

I would like to know how much gain in horse power will I see from these mods?

1: Simota Intake V2? (Did some search and I found that Simota Intake CB2 provides 10ish HP but... can't find any data on V2 but it says around 5 more than Gruppe M)
Price: 550USD

2: Muffler delete (Read from somewhere it is 10?)
Price: 80-130USD

3: LET Tune (10ish)
Price: 350-450USD

Please confirm if those are true ... Thanks!

Nothing gives gains for NA e90s. Might as well just go cosmetics, and get some lightweight stuff that will reduce the body weight.

lol just get the intake and the tune and that should be good. muffler delete i think increases hp but decreases torque... its basically for sound.
