328ci exhaust question

Looking to upgrade my exhaust on my 328ci and add a little power. Interested in the AA Gen 3 High Flow, but a friend told me straight pipes will get the same sound.
Question is will the straight pipes add any hp?
Also what other exhausts would give a deeper sound and power increase?

Not many cat back exhausts will give an power increase really. If you do headers, it's dynoed to add about an extra 15hp.

Straight pipes with stock muffler will give an deep aggressive sound but no power increase.

from my experience...after ebay headers & full Cat back (Highline) it kicks, smells and farts....and yes the car rolls a little more even after I stop gasing.

thanks for the responses

Silly question:
Is "resonator deleting" simply cutting out a resonator or what??

^ Yup- you will need a shop that knows what they're doing. Otherwise the wrong parts will be cut and it will get messy.
