It wont produce any seat of the pants power but every little bit helps in the quest for more power.

Anything you can do to free up the exhaust, will create power.

Very little power, mostly sound.

What kind of sound difference will it make? I've got a magnaflow axel back and I'm looking for a little more volume, will removing the secondary cats add volume or just change the tone?
