    Stage I
High Flow Exhaust System with Street Cannons is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Beautiful deep sound & fantastic looking! I had my dealer put these pipes on my new 2016 Street Glide Special along with the high flow intake. These have a real nice low tone to them and I can tell a big difference between the stock pipes. I had to do the tune myself because I purchased a Power Commander V tuner and my dealer would only tune the street tuners. It was real easy, there was a tune already online for Scremin Eagle pipes and intake. The pipes you can get today are not what you could get a few years ago. The EPA has choked down on the loud pipes of yesterday. On my 09 Road King I had the Vance & Hines Big Radius, and those were loud! With these high flow pipes the sound is not too loud and I can hear my radio system just fine.

I just bought a 2015 street glide special, it has the High Flow Exhaust System. How do I clean the pipes?

Asked by: DLD59

Does this system void the factory and extended warranties? So would the street tuner be needed with this upgrade and would that void any warranties?

Asked by: Dmd25

How much louder is this system compared to stock header and reagular street cannon muffler ?
