Now I have my own dyno graph with Streetmaster pipe
Great idle sound & righteous H-D sound under load. Some say not easy to accomplish with M8. Loud but not obnoxious. Sound clips don't do it justice. I did SE stage 3. stock 10.5-1 107ci to 11-1 114ci with new bike and Streetmaster to retain full H-D warranty. Stock about 77 WHP, H-D chart stage 3 about 108 WHP with Street Cannon, mine 116 WHP. Stoked.
I would recommend this product
