If you get the pipe and the jet kit and add them both, then this is the best combination for performance. If you are looking for a good pipe, but dont like the LOUDNESS.. I put the HMF QS1 ECO System pipe on the wife's bike and she absolutely loves it. She gets the performance as well as a nice sound. She hates loud and obnoxious...like mine, but this is perfect for her..
