It is decent but there are better pipes for overall power gains . I used to have a FMF Powercore IV2 slip on and it never gave me problems. I liked how it was very light and had a unique sound to it.

The powercore was my first slip on and it was a good pipe. It had a great sound, which I like more than my HMF, and the value was good as well. It added some low end grunt but for the most part there was not much of a performance gain with it.
