M4 Performance Exhaust has released a new slip-on for the 06-07 GSX-R600/750. That's right, you read correct, it's for the 06-07. I like to see companies going back to fill a demand in the market and this is a wonderful looking and sounding slip-on exhaust in my opinion. The super-short muffler tucks away beautifully and works well with the lines of the motorcycle. This slip-on comes with a quite insert installed so the neighbors don't complain about the noise.
