All you are going to accomplish by cutting off the mufflers is make more noise. It's not really going to improve performance. If you want to do it right, get a proper cat-back system and high flow cats.

You must be talking about the intake mufflers? I'm not sure if there are any real gains. Some say it creates an intake drone at certain speeds or under tow/load.
