    Stage I
High-Flow Exhaust System with Street Cannon Mufflers is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Excellent exhaust for performance without excessive noise The addition of this exhaust, performance breather, and tuner to my 2018 Road Glide Special increased my HP and torque numbers by over 15 each! The power is immediate and consistent throughout the entire RPM range. The exhaust sound is deeper and slightly louder than stock. I'm very pleased with this product.

Rated 4 out of 5 by from High Flow = Performance If you want real performance gains and not just more noise spend the extra money over the slip ons and get the high flow exhaust system; headers, relocated cats and street cannons = a lot more power potential compared to just mufflers alone. I come from a car guy background including a 725hp racing Subaru and a 600hp street driven Challenger and they both had something in common with this high flow system; you start with headers, cats and mufflers to make sure your exhaust system isn't a bottleneck. I also purchased the prostreet tuner, smart tune and heavy breather air cleaner. The combination really woke the bike up. Before it struggled to manage its 800+lbs, now off idle roll on is crisp, strong and smooth, acceleration noticeably faster and overall the bike just feels so much better. I was a little disappointed that it was so quiet, it sounds only a little louder than stock. Other than that, a great unit.

What are the gains vs stock? Sound clip?

What are the numbers vs stock? I'd like to see some dyno figures. Will there be any sound clips or videos?
