Non-Resonated Pipe Method:

With this method we cut open the centre chamber of the muffler which houses the perforated pipes and muffler baffling. What we do is cut out the perforated pipe and replace it with a solid traditional pipe and re pack the baffling. What this does is isolate the sound waves to channel through the pipes opposed to letting it getting absorbed or muffled (hence the name muffler).
