This is a great little hack.
I ran a pipe I think 1 inch, that bypassed the muffler.
So some of the exhaust gasses ran around the muffler and where un muffled. SO the sound is louder.
This is my video of the PSE on an unmodified 2.5

Here is a link showing the directions for this hack:

Out of all of the muffler systems for the 2.5 I have heard the Pedro SE is my favorite. The only reason I removed it is that I placed the tips from my straight pipes on my oem muffler and the tips looked like ass. I came across a great deal on a maxspeed muffler and jumped on it.
The maxspeed muffler is too quiet for me....I guess something about have turboes inline makes the exhaust quieter. Since its quiet for my taste I will work on a new muffler hack.
Back to the question at hand. The PSE is a great simple $100 hack. I would try it before spending any money on a muffler.
Power gains...possible but do it for the sound.
