 Awsome look and great fit and finish.

 Great product, really increased the performance of my HD Street Bob.

 Looks great on my Fat Bob and added to an already beefy performer!
JP, Massachusetts
 I had purchased this system for my 2007 Harley and I am happy with the results of it especially out of the hole power due to its ability to breath better with this filter.
