Idk. I just looked at the dyno videos for the ECU upgrade and secondary cat bypass pipes from fabspeed motorsports on youtube. They did add roughly 17-20HP with the exhaust and ECU as well as a BMC Air Filter. Was guessing a Evo or Agency Power Cold Air Intake would add 2-3HP more than a BMC performance Air filter so that is how I reached 20-25HP.

As Fabspeed advertises.
8HP and torque for bypass pipes
10-12 HP for ECU Upgrade
Up to 5HP on BMC Filter(my guess is more like 1-2)

No offensive, but Fabspeed would love all of us to believe that their by-pass pipes and ecu program accomplishes those figures. Realistically, however, once a person has completed his or her upgrades, a good ecu tune more or less "tweaks" the air/fuel parameters . In turn, this can create better engine response and fuel efficiency . The actual gain is hp is negligible . As far as the effectiveness of bypass pipes are concerned, one can shed a good deal of weight from the vehicle, as well as open up exhaust flow which is caused by the restrictive nature of oem secondary cats. Again, this equates into a very little actual hp gain . It's probably the drop in BMC filter that gives things a slight bump . LOL !

Is BMC really that good? I hear lots of good things about it. Much better than a K&N filter, right?

I've had good results with one . However, nowadays I have the EVO high flow air intake on my vehicle . It's all about the sound !
