I loved the looks of my HK's I had but didn't care for the sound. I made several baffles for them and finally got close to what I wanted. The HK's chrome is great and they are made of real heavy metal so they stand up well. I finally got my used Bubs and love them so much that when I found a set of brand new ones at less than I paid for my used ones I bought them. I love my Bubs the sound is great and the performace increased by 7 hp
. It all depends on what you want. HK's are a real quality pipe.
